Answer

The structural isomers for C4H9Cl include:

1-chlorobutane:
2-chlorobutane:
2-methyl-1-chloropropane:
2-methyl-2-chloropropane:

All structural formulas represent the same chemical formula C4H9Cl with different arrangements of chlorine and the carbon chain.

Step 2

Give the name or formula of a suitable laboratory oxidising agent for the reaction of 1-butanol to a carboxylic acid.

Answer

A suitable oxidising agent for the conversion of 1-butanol to a carboxylic acid is potassium dichromate (K2Cr2O7), commonly used in organic chemistry for alcohol oxidation.

Step 3

Give the systematic name for the carboxylic acid.
