A hydrocarbon (P) has the molecular formula C₁₀H₂₂. A hydrocarbon (Q) has two carbon atoms less than (P) and belong to the same homologous series. A hydrocarbon (R) has two carbon atoms more than (P) and belong to the same homologous series.

(i) What is the molecular formula of (Q)?
(a) C₁₂H₂₆
(b) C₈H₁₆
(c) C₈H₁₈
(d) C₈H₁₄

(ii) To which homologous series do the compound (P), (Q) and (R) belong?
(a) C_nH_2n
(b) C₂H2_{n – 2}
(c) C_nH_{2n + 2}
(d) C_nH_{2n + 1}

(iii) What is the molecular formula of (R)?
(a) C₁₂H₂₆
(b) C₁₂H₂₄
(c) C₁₂H₂₂
(d) C₁₂H₂₈

(iv) Identify the correct statement about compounds (P), (Q) and (R).
(a) They have same melting and boiling points.
(b) They have same chemical properties.
(c) They have different general formula.
(d) They differ by —CH₂ unit.

(v) Compounds (P), (Q) and (R) are
(a) alkanes
(b) alkenes
(c) alkynes
(d) none of these.

Answers:

(i) (c): Molecular formula of (Q) is C₈H₁₈ as it has two carbon atoms less than (P).
(ii) (c): Compounds (P), (Q) and (R) are alkanes having general formula C_nH_2n+2.
(iii) (a): Molecular formula of (R) is C₁₂H₂₆ as it has two carbon atoms more than (P).
(iv) (b): Compound (P), (Q) and (R) belong to same homologous series so they have different physical properties but similar chemical properties. They have same general formula C_nH_2n+2. They differ by 2 carbon atoms and 4 hydrogen atoms.
(v) (a)
