Question

A number of functional group and degree of unsaturation (respectively) in the above compounds is:

• A. $7,8$
• B. $6,8$
• C. $6,6$
• D. $5,6$

Answer 1

The correct option is B $6,8$

Function Groups are:

$O$ $O$

$-\stackrel{||}{C}-NH-$ , $-\stackrel{||}{C}-N{H}_2$, $-COOH$, $-O-$, $-NH-$, $-C\equiv CH$ .

Hence, only $6$ functional groups.

Degree of unsaturation is $8$ ($3$ Rings+ $3$ Double bonds+ $1$ Triple bond)
