Question

What is indicated by the methyl-prefix?

Answer 1

Answer:

The molecule is a branched hydrocarbon.

Explanation:

Answer 2

The methyl prefix indicate the presence of a single carbon or the molecule is a branched hydrocarbon.

Prefix in IUPAC Nomenclature

The Prefix is used to show or indicate the substituents, side chains of the molecule and prefix attached to the beginning of a word and the molecules name is based on the number of carbon atoms in IUPAC nomenclature.  The International Union of Pure and Applied Chemistry (IUPAC).

For Example:

Number of carbon Atoms          Root Name                  Prefix (side group)

1                                                    meth-                             methyl-

2                                                   eth-                                ethyl-

3                                                   prop-                              propyl-

4                                                   but-                                 butyl-

5                                                   pent-                               pentyl-

6                                                   hex-                                 hexyl-

7                                                   hept-                                heptyl-

Thus, we can say that prefix tells us the number of carbon atoms in each molecule. A presence of single carbon is indicated by the methyl prefix or we can also say that the molecule is branched hydrocarbon.
