1.	A hydrocarbon `(A)` was found to have vapour density `36`. If forms only a single monochloro substitution product. Suggest `(A)`.
Answer» Correct Answer - Mol. Wt of alkane `=` Vapour density `xx2=36xx2=72` Alkane is `C_(n)H_(2n+2)` `therefore 12n+2n+2=72` `therefore n=5 therefore` Alknae is `C_(5)H_(12)` Thus alkane `C_(5)H_(12)` showing only one mono substitution product is `CH_(3)-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)C-CH_(3)overset(Cl_(2))rarrCH_(3)-underset(CH_(3))underset(\|)overset(CH_(3))overset(\|)C-C_(2)Cl` (A) (2,2-`dimethylpropane)
