Question

Name the alkyne. Spelling and punctuation count. A seven carbon chain with a triple bond between carbon 1 and carbon 2. There is a C H 2 C H 2 C H 3 group attached to carbon 3.

Answer 1

Answer: IUPAC name of $CH\equiv C-CH_2-CH_2-CH_2-CH_2-CH_3$ will be hept-1-yne.

Explanation:

The IUPAC nomenclature of organic compounds are given as follows:

1. Select the longest possible carbon chain.

2. For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'hept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.

3. A suffix 'yne' is added at the end of the name if triple bond is present.

$CH\equiv C-CH_2-CH_2-CH_2-CH_2-CH_3$

The IUPAC name will be hept-1-yne.
