(a)(a) Alkanes (CAlkanes (CnnHH2n+22n+2))
Alkanes are hydrocarbons that contain only C – C and C – H single bonds(except CH4)
Relatively inert as the bonds are strong
saturated hydrocarbons
contain the maximum possible number of hydrogen atoms per molecule

Cycloalkanes in skeletal forms
Most stable due to less angle strain
Angle strain arises from repulsions between adjacent bond pairs

Starting from C4H10, two or more structures are possible for the same molecular formula.
This phenomenon is called isomerism.
The different structures with the same molecular formula are called isomers.
