Question

Use the following chemical formulas and classify each compound as an acylic alkane or a cyclic alkane. CaHs Acyclic alkanes: C6H14 C12H24 CsHo C.H12 Cyclic alkanes: CsH2 C10 H22 CH16

Answer 1

A cyclic alkane has the molecular formula = C_nH_2n

A acyclic alkane has the molecular formula = C_nH_2n+2

so now putting all these in formula

i)   C₄H₈

C₄H_4×2 =C₄H₈    so it is cyclic alkane

ii) C₆H₁₄

   C₆H_2×6+2 = C₆H₁₄ it is acyclic alkane

iii) C₁₂H₂₄

C₁₂H_12×2 =C₁₂H₂₄    so it is cyclic alkane

iv) C₃H₆

C₃H_3×2 =C₃H₆    so it is cyclic alkane

v) C₆H₁₂

C₆H_6×2 =C₆H₁₂    so it is cyclic alkane

vi) C₅H₁₂

   C₅H_2×5+2 = C₅H₁₂ it is acyclic alkane

vii) C₁₀H₂₂

   C₁₀H_2×10+2 = C₁₀H₂₂ it is acyclic alkane

viii) C₇H₁₆

   C₇H_2×7+2 = C₇H₁₆ it is acyclic alkane
