Question 1
1 / -0

What will be the prefix in the following compound ?
$$HOOC - CH-2 - \overset{\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!HOOC - CH_2}{\overset{\!\!\!\!\!|}{CH}} - CH_2 - CH_2 - COOH$$

A
$$methycarboxy$$

B
$$carboxymethyl$$

C
$$carboxyethyl$$

D
$$ethylcarboxy$$

Solution

$$2$$,-carboxymethyl hexanedioic acid
Question 2
1 / -0

1-butyne reacts with cold alkaline $$KMn{O_4}$$ to produce

A
$$C{H_3}C{H_2}C{H_2}COOH$$

B
$$C{H_3}C{H_2}COOH$$

C
$$C{H_3}C{H_2}COOH + C{O_2}$$

D
$$C{H_3}C{H_2}COOH + HCOOH$$

Solution

Terminal alkynes on oxidation give a mixture of $$CO_2$$ and a carboxylic acid with one $$C-$$ atom less than that of the starting alkyne.

$$CH_3-CH_2-C\equiv CH \xrightarrow{alk. KMnO_4} CH_3-CH_2-COOH+CO_2$$
