3.
Molecular formula: It consists of the chemical symbols for the consitutents elements, number of atoms present in the molecule are denoted by numeric subscripts .
Example: CH3Cl.
Structural formula : It provides the arrangement of atoms in a molecule.
Example: 
Molecular models:
It is 3D arrangements of atoms in a molecule.
4.
Geometry of alkane is tetrahedral, hence in 3D model the compound can not represented as straight line.
5.
6.
alcohol has OH group.
ether has -O- group.
aldehyde has -CHO group.
Ketone has RCOR group.
Carboxylic acid has -COOH group.
7.
From the name of a molecule three important things can be learned
1. Number of carbon atoms.
2. Presence of subsitutents in the carbon chain.
3. Presence of functional group.
8.
cyclohexane and benzene both are cyclic .
Difference : cyclohexane is nonaromatic saturated hydrocarbon.
