Naming a branched alkane

Step $2.$ Identify and name the branches on the longest continuous chain.

Names of branches $($alkyl groups$)$ are derived from the name of the alkane with the same number of carbons by replacing the suffix "ane" with $"$yl$."$ e$.$g$.,-C{H}_2-C{H}_2-C{H}_3$ is propane $-$ ane $+yl=$ propyl

When multiple branches are present they are named in alphabetical order $($e$.$g$.$ butylmethyl, not methylbutyl$).$

The name for this branch is
