Answer 2

The question is incomplete here, therefore I will just explain how to find the structural formula with iupac name generally.

Answer with explanation:

1. alkanes: general formula is CₙH₂ₙ₊₂ and suffix is ane

if number of carbons is 1- IUPAC name Methane

C-2-Ethane

C-3 propane

C-4-butane

C-5-pentane

C-6-Hexane

C-7-Heptane

C-8-Octane

C-9-Nanane

C-10-Decane

2. Alkenes: general formula is CₙH₂ₙ and suffix is ene

number of carbons and IUPAC names are as follows

C-1- No compound exists

C-2-Ethene

C-3-Propene

C-4-Butene

C-5-Pentene

C-6-Hexene

C-7-Heptene

C-8-Octene

C-9-Nanene

C-10-Decene

3. alkynes- general formula is CₙH₂ₙ₋₂, suffix is yne

C-1- No compound exists

C-2-Ethyne or acetylene

and IUPAC follows same as Alkane and alkene with suffix yne

similar to these the suffix of few other organic compounds are mentioned below

4-cyanide- prefix- Isocyanide and suffix- isonitrile

5-aldehydes- suffix- al

6-carboxylic acid-suffix-Oic acid

7-amides- suffix-amide or caboxamide and prefix-amido
