The structures of all isomeric alcohols of C5H12O are given below:
Naming is done by the conventional method. The -OH group is attached on the first carbon.
(b) 3-Methylbutan-1-ol
Butane is the longest chain and methyl is the substituent group.
(c) 3-Methylbutan-1-ol
the longest chain is butane and conventional naming method is used.
(d) 2,2-Dimethylpropan-1-ol
Isomer is made by transforming the principal carbon into tertiary type. The longest chain is butane and named accordingly.
(e) Pentan-2-ol
the longest chain is pentane and the numbering is chosen from the minimum position.
Butane is the longest chain, further numbering is done b

Nitroethoxide ion (O2NCH2CH2O–) is more stable than ethoxide ion (CH3CH2O–) due to -I effect of nitro group which decreases the negative charge of oxide ion of nitroethoxide ion leading to stability. In contrast, CH3CH2 has +I-effect. It, therefore, tends to intensify the -ve charge and hence destabilizes it.

Butane is the longest chain.
Propane is principle chain and substituents are numbered accordingly.
Hexane is the longest chain. There are three -OH substituents and 2 methyl groups.
-OH of phenol is numbered a 1.
Propane is the principle chain and the alkoxy group is ethyl group.
the longest chain is pentane and substituents are numbered accordingly.
In such cases, cyclo groups are named first, followed by conventional naming methods.
The cyclo group is named first, followed by conventional naming methods.
Cyclo group is named first. Pentane having a double bond is named then with the suffix -OL added to the end.
The longest chain is buta

(a) 2, 2-Demethylpentane
(b) 2, 4, 7-Trimethyloctane. For two alkyl groups on the same carbon its locant is repeated twice, 2, 4, 7-locant set is lower than 2, 5, 7.
(c) 2- Chloro-4-methylpentane. Alphabetical order of substituents, (d) But-3-yn-1-ol. Lower locant for the principal functional group, i.e., alcohol.
