succinic acid

B

benzylchloride

C

benzaldehyde

D

adipic acid

Answer

adipic acid

Explanation

Solution

Nylon-66 is prepared from monomers, adipic aeid and hexamethylene diamine by condensation process. H2N−(CH2)6−NH2+HOOC−(CH2)6−COOH→tNH−(CH2)6−NH−CO−(CH2)6−CO−]nH _{2} N -\left( CH _{2}\right)_{6}- NH _{2}+ HOOC -\left( CH _{2}\right)_{6}- COOH \rightarrow \left. t NH -\left( CH _{2}\right)_{6}- NH - CO -\left( CH _{2}\right)_{6}- CO -\right]_{n} Nylon - 66
