10) The figure below represents an endothermic spontaneous reaction What are the signs (+, or-) of ??, as, and AG for this process? 11) The following plot shows a typical titration curve for the titration of diprotic acid H A (Kal 1.2x10-4, Ka2-2.1x1010 with NaOH Given that the principal A-containing species at the equivalence point HA- Moles of oH- added A buffer region is indicated by which of these point(s) a-d in the titration curve? ints a and b points a and c b. d. points b and d points c and d e. Solution Answer -10 Endothermic spontaneous process. Delta H must be positive as heat supplied to the system. Delta S is also positive as reaction is spontaneous. G is negative for spontaneous recation. Hence option D is correct. 11. The slope of point a and c is very less than other ponits hence it shows eqvilance point.. Correct option is b. .

1.Put the ionic compounds in order of smallest to largest lattice energy LiCl Al2O3 KCl SrS 2. A____bond is the result of nonmetals having high ionization energies A_____bond has non-localized electrons A_____bond results due to decrease in potential energy when opposite charged species come together Solution 1. Higher charge and smaller size of ions result in compounds with large lattice energy. Of the given compounds, Al 2 O 3 has Al 3+ and O 2- have largest charge and thus highest lattice energy. Next SrS has Sr 2+ and S 2- which is the next highest charge present in the list. Then comes LiCl and KCl. Of these, Li + has smaller size than K + and thus it will have a higher lattice energy. Thus the final order of lattice energy is, Al 2 O 3 > SrS > LiCl > KCl (highest to lowest) 2. A covalent bond is a result of non-metals having high ionization energies. Hence they do not ionize but share electrons. . A pi bond has non-localized electrons. The pi-electrons form a diffused cloud in the molecule that can be easily distorted. A ionic bond results due to decrease in potential energy when oppositely charged ions come together. Mutual electrostatic attraction is what keeps the molecule together. .

10) Which species acts as the nucleophile in the reaction of 1-butene with bromine water? A. a hydronium ion B. elemental bromine C. water D. a bromide ion (O 11) Which of the following is the least likely to react with an alkene? A. elemental bromine B. a hydronium ion C. potassium permanganate D. an ethyl radical e)sodium methoxide uant uceur 12) What will be formed when 1,2-dimethylcyclopentene is reacted with hydrogen gas in the presence of palladium? A. a mixture of mostly trans-1,2-dimethylcyclopentane and a smaller amount of cis-1,2 dimethylcyclopentane only cis-1,.2.dimethylcyclopentane 2 cis produdt Orv C. only trans-1,2-dimethylcyclopentane D. a mixture of mostly cis-1,2-dimethylcyclopentane and a smaller amount of trans-1,2 dimethylcyclopentane 13) Which of the following is the major product formed after 1-methylcyclopentene undergoes acid catalyzed hydration? ?? ?? ?? ?? Solution 10. Option C water since it is an example for halo hydrin formation reaction. First step is the formation of cyclic bromonium ion then ring opening by water. 11. Option E, since sodium ethoxide exists as EtO-& Na+ Both alkene and Ethoxide are Nucleophilic in nature due hence no reaction between them. 12. Option B since hydrogenation is Cis, both hydrogens will add from the same side of double bond. 13. Option C, more substituted alcohol is the major since it is made from more stable tertiary carbocation. .

1-) What are the tax concepts involved in completing the Form 1040? Explain in detail. 2-) What are the tax planning considerations you took into account while completing the Form 1040? 3-) What are the various steps and the calculations for each step you made while completing the Form 1040? Solution 1. The form 1040 shall be filed by an individual liable to pay taxed by the 15yh of April. The another name of this form is long form or U.S. Individual income tax return. It contains a number of pages in which financial ststus of the income of the individual is disclosed. It discloses whether the individual has to pay taxes or he gets refund. There are number of forms 1040 like 1040EZ etc. 2. While completing form 1040 we made tax planning in such a way that the tax payable is minimum but with the compliance of all the rules and regulations. For tax planning significant amounts are invested in funds like life Insurance Policies, Mediclaim of the self and the parents etc. As deductions are allowed under these sections. Tax is payable if the income after reducing certain deductions is chargeable to taxes. 3. It includes penalties aginst a taxpayer who doen not compliance with the laws & also includes taxability of wages, salaries tips and other things etc & deductions and credits like medical and dental expenses. It includes collection of the the taxpayers filing information& requirements of filing. The return should be throughly checked for the completeness and the accuracy & the tax payable and refund due should be properly calculated. .

1. Why does the initially formed copper hydroxide precipitate dissolve upon addition of aqueous ammonia while synthesizing copper(II) acetate monohydrate? 2. Melting points and boiling points of compounds usually increase with increasing molecular weight, but the hexamethylcyclotrisiloxane is a solid at room temp and octamethylcyclotetrasiloxane is a liquid. Why might cyclotrimer be an exception to the normal rule Solution 1. When concentrated ammonia solution is slowly added in a light blue, aqueous solution of copper( II) chloride, there is formation of, light blue precipitate of copper(II) hydroxide. Further excess addition of ammonia causes the Cu +2 ions to go back into solution and hence continued addition of ammonia results the formation of a soluble deep blue complex copper ammonia ion means initially formed copper hydroxide precipitate dissolve upon addition of aqueous ammonia at this stage. 2. Tghis is due to the difference in arrangement oof molecules in a compound means the crystal lattic. The crystal lattice of has highly cross-links structure. .
