Respuesta :
C) They have more than two carbons that are bonded to only one other carbon
The statement of characteristic of branched chain alkanes is "they have carbon atoms that are double-bonded to other carbon atoms."
What is branched chain alkanes?
An alkane with alkyl groups connected to its central carbon chain is termed as a branched chain alkane or branched alkane. Straight chains do not exist in all hydrocarbons. Branched hydrocarbons are hydrocarbons that have branches of C atoms connected to a chain. Side chains are connected to a continuous carbon chain in branched chain alkanes.
Branched alkanes are molecules that contain only hydrogen and carbon (H and C) atoms, with carbon atoms joined to adjacent carbon atoms by single bonds only (methyl, ethyl, etc.).
Hence, the correct answer is they have more than two carbons that are bonded to only one other carbon.
