Q1P-a - Organic Chemistry (Mcmurry)

Question

Give IUPAC names for the following alkyl halide (a):

(a)

Step-by-Step Solution

Answer

(a)The name of the compound (a) is 1-Iodobutane.

Step 1: Nomenclature of Alkyl halides

IUPAC rules used for naming of Alkyl halides

• Select longest carbon chain, it is the parent chain;
• Longest chain must contain double or triple bond, if present;
• Number the alkyl or halo substituent carbon i.e. it should possess lowest number in the parent chain;
• Assign a number to each substituent;
• Write the name of substituent’s in alphabetical order while naming

Step 2: Nomenclature of alkyl halides

(a) The name of the compound is 1-Iodobutane.

As the chemical structure indicates, that the given alkyl halide has four carbon atoms in the parent chain, so it is termed as butane.

It is having iodine group attached at first position, so it is 1-iodobutane.
