Write the molecular formula of: (i) an alkane (ii) an alkene, and (iii) an alkyne, each having 20 carbon atoms?

Question

Philoid · Accepted Answer

(i) The molecular formula of al alkane is C_nH_2n+2. Here, n is number of carbon atoms.

If number of carbon atoms (n)=20

Then, the molecular formula of alkane is C₂₀H₄₂.

(ii) The molecular formula of al alkene is C_nH_2n. Here, n is number of carbon atoms.

If number of carbon atoms (n)=20

Then, the molecular formula of alkene is C₂₀H₄₀.

(iii) The molecular formula of al alkyne is C_nH_2n-2. Here, n is number of carbon atoms.

If number of carbon atoms (n)=20

Then, the molecular formula of alkyne is C₂₀H₃₈.
