3. all the following steps need to be followed when naming alkanes, except a. locating the longest carbon chain. b. using prefixes to designate identical branches. c. placing the name in alphabetic order ignoring the added prefixes. d. beginning numbering at the end farther from the first branch.

D. beginning numbering at the end farther from the first branch.

Explanation:

In naming alkanes, the longest continuous chain in the compound is first considered and this gives the name of the compound intended. The name of the substituent on the compound are also arranged in alphabetical order when naming the compound.

The carbon atoms are numbered in the parent chain or ring to indicate where branching or substitution takes place. The direction of numbering is chosen such that the lowest numbers possible is given to the branches or substituents. If we begin the numbering at the end farther from the first branch, we won't give the lowest numbers possible to the branches.
