Question

Consider the following statements :
(a) All hydrocarbons show phenomena of isomerism.
(b) The members of a homologous series have similar chemical and physical properties.
(c) Cyclic hydrocarbons are saturated or unsaturated organic compounds that contain ring of carbon atoms.
(d) Synthetic detergents are sodium or potassium salts of long chain carboxylic acids.
Which of the above statement(s) is/are correct?

• A. Only (c)
• B. Only (d)
• C. (a),(b) and (c)
• D. (a),(c) and (d)

Answer 1

The correct option is A Only (c)

All hydrocarbons do not show isomerism. Members of a homologous series possess similar chemical properties only. Sodium salts of long-chain aliphatic or aromatic sulfonic acids are used as detergents.
Hence only (c) option is correct.
