Question

What is the information given by the IUPAC name of an organic compound ?​

Answer 1

$\Huge{\sf{\red{Answer:-}}}$

The IUPAC name of an organic compound gives information about:

a) The number of carbon atoms present in the molecules we call this part of the name as word root.

b) The substituent in the molecule; Prefix.

c) The functional group in the molecule; Suffix.

Prefix: Prefix has parts like primary prefix, secondary prefix, numerical prefix etc.

d) Primary prefix is 'cyclo' and it is useful only for cyclic compounds.

e) Secondary prefix for halogens substituents, written as halo,alkyl,alkoxy etc.

Suffix: It has some parts like primary suffix, secondary suffix, numerical suffix and number suffix etc.

1) Primary suffix tells about

(C-C) $\rightarrow$ ane

(C=C) $\rightarrow$ ene

(C=-C) $\rightarrow$ yne etc.

2) Secondary suffix tells about the functional groups with the particular term.

example:

hydrocarbons 'e'

Alcohols - 'ol'

Aldehydes - 'al'

Kentones - 'one'

Carboxylic acid - 'oic acid, etc.

3) Numerical prefixes $\rightarrow$ di,tri etc.

4) Numbers are written to tell about to which carbon atoms of the compound the substituent (s), multiple bond (s), or functional group(s) are attached.

Answer 2

Answer:

The IUPAC name of an organic compound gives information about:

a) The number of carbon atoms present in the molecules we call this part of the name as word root.

b) The substituent in the molecule; Prefix.

c) The functional group in the molecule; Suffix.

e) Secondary prefix for halogens substituents, written as halo,alkyl,alkoxy etc.

Suffix: It has some parts like primary suffix, secondary suffix, numerical suffix and number suffix etc.

1) Primary suffix tells about

(C-C) \rightarrow→ ane

(C=C) \rightarrow→ ene

(C=-C) \rightarrow→ yne etc.

2) Secondary suffix tells about the functional groups with the particular term.

example:

hydrocarbons 'e'

Alcohols - 'ol'

Aldehydes - 'al'

Kentones - 'one'

Carboxylic acid - 'oic acid, etc.

3) Numerical prefixes \rightarrow→ di,tri etc.

4) Numbers are written to tell about to which carbon atoms of the compound the substituent (s), multiple bond (s), or functional group(s) are attached.
