Question

what are the names of following compounds ch3ch2oh, c6h10

Answer 1

$\boxed{\sf{ANSWER}}$

$CH_{3}CH_{2}OH \implies \bf{Ethanol}$

$C_{6}H_{10} \implies \bf{Ethyne}$

___________________________________________

The names of these compounds are determined by nomenclature.

• First count the total number of carbons
• meth-one carbon
• eth-two carbons
• prop-three .......
• but-four............
• pent-five........
• hex-six............
• Then see the functional groups if any.

$CH_{3}CH_{2}OH$

1. This compound has -OH- group.
2. It has 2 carbon atoms also.
3. The OH group is alcohol.

Thus it can be written as ethanol.

$C_{6}H_{10}$

1. There are 6 carbons
2. Let me tell you that :

If  $C_{x}H_{y}$  is a compound of hydrocarbons then ..

• If x=6 and y=10 then x=2 y-2
• 6=12-2 obviously.
• Also multiply 2 with number of carbon atoms
• Remember if the number of H atoms is twice the C atoms then it is alkene.
• If less it is alkyne and if more then it is alkane.
• Here 12>10 so it is alkynes.
• Hence the beautiful name ethyne

Ethyne is the name.

Hope it helps you
