Match the general formula from Column I with the class they belong to in column II

	Column–I		Column–II
i		p	Has tertiary N–atom
ii		q	Has tertiary carbon atom
iii		r	Has five carbons in the parent chain
iv		s	Has two carbons in the parent chain

$\left(i\right)\to (p,q,r)$

Is has  $3°N-$ Atom. Parent chain has five carbon. It has $C-4$ and $C-2$ Tertiary carbon

$\left(ii\right)\to (q,r)$

It has no tertiary N-atom. C-2 and C-4 are tertiary carbon. Parent chain has 5 carbon

(iii)(p,r)

Its nitrogen is tertiary. Parent chain has five carbon

$\left(iv\right)\to \left(qs\right)$ It has two tertiary carbon. Parent chain has only two carbon
