Which of the following is the correct condensed structural formula for pentane?
A
B
C
D
Verified step by step guidance1
Step 1: Understand that pentane is an alkane with 5 carbon atoms connected in a straight chain, and alkanes have the general formula \(C_nH_{2n+2}\).
Step 2: Write the condensed structural formula by connecting 5 carbon atoms with single bonds, ensuring that each carbon has enough hydrogen atoms to satisfy the tetravalency (4 bonds) of carbon.
Step 3: For the terminal carbons (the first and last carbon atoms), assign 3 hydrogen atoms each, since they are bonded to only one carbon atom.
Step 4: For the internal carbon atoms (the three carbons in the middle), assign 2 hydrogen atoms each, as they are bonded to two other carbon atoms.
Step 5: Combine these groups to write the condensed formula as \(C\_H_3-C\_H_2-C\_H_2-C\_H_2-C\_H_3\), representing the straight-chain pentane molecule.
