Concept introduction:
Different isomers can be arrived by arranging the carbons present in the molecule as a straight chain or as a branched chain with one or two branches and placing the
The names of simple carboxylic acids which are derivatives of open-chain
To give:
The structure and names of eight carboxylic acids with the formula C6H12O2.
b) Three nitriles with the formula C5H7N
Interpretation:
The structure and names of three nitriles with the formula C5H7N are to be given.
Concept introduction:
Different isomers can be arrived by arranging the carbons present in the molecule as a straight chain or as a branched chain with one or two branches and placing the functional group on different carbons in the chain.
Simple open chain nitriles are are named by adding –nitrile as suffix to the alkane name, with the nitrile carbon numbered as C1. Nitriles can also be names as derivatives of carboxylic acids by replacing the –ic acid or –oic acid ending with –onitrile. The nitrile carbon is not numbered but the carbon to which it is attached is numbered ac C1. If another carboxylic acid derivative is present in the same molecule, the prefix –cyano is used for the –CN group.
To give:
The structure and names of three nitriles with the formula C5H7N.
