vasudevrathod: its the same compound which sir give us

lavateharshada21: Do you want the IUPAC names?

TPS: so what do you want?

vasudevrathod: we have to name these compounds

vasudevrathod: i am confused how to name

lavateharshada21: But, there are more than one names for these compounds as they don't have hydrogen atoms. The question is incomplete.

vasudevrathod: you can give any name just please explain how

lavateharshada21: Okay... let's see...

lavateharshada21: Do you want the IUPAC names or common names?

TPS: Use H atoms whereever required.. skeleton formula is given like that only

Try to solve the other questions in the same way. I will give you the answers.

2.) 2, 4 - Dimethyl pentene
(We write the suffix '-ene' as a double bond is present.)

3.) 2, 4 - Dimethyl pentane

4.) 3 - Butyl - 2 - methyl heptane
(the longest chain has seven carbon atoms.)

Here, you are given skeleton structure of the molecules. To know the complete structures, attach H atoms to the carbon atoms wherever it is necessary to satisfy its tetra valency.

For example, C - C is the skeleton structure for ethane, which is C2H6.

So here,

1.
First molecule given has 4 carbons in the longest chain.

It is 2,2-dimethyl butane

2.
Second molecule has 5 carbons in the longest chain with a double bond. C with double bond will be number one C atom in the chain.

It is 2,4-dimethyl pent-1-ene

3.
Third molecule has 5 carbons in the longest chain.

it is 2,3-dimethyl pentane

4.
Fourth one has 7 carbons in its longest chain.

it is 3-butyl 2-methyl heptane
