1 sigma 0 p 20) Boyle's Law is expressed as a) Visproportinnal b) P is proportional to V c) V is
propertional to T d> Vis proportional to e) none of the above 1) The initial volume d a gas
cylinder ib 7500 ml. Y the pressure of a gas ineide the cylinder changes from sen, mm Hg to
3600 mm Hgwhat i.the final volun. O r?s nopin a) 3214 ml b) 3.151 L d) 6300 ml e) none of the
above
Solution
18)
I forms 3 sigma bonds. Pi bonds are not considered in hybridisation
So, it is sp2 hybridised
II forms 4 sigma bonds.
So, it is sp3 hybridised
III forms 3 sigma bonds and has 1 lone pair.
So, it is sp3 hybridised
Answer: c
19)
double bond has 1 sigma and 1 pi bond
triple bond has 1 sigma and 2 pi bonds
Answer: c
