(a)

Interpretation Introduction

Interpretation:

The structural formula of 2,3-Dimethylcyclobutane should be drawn.

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Saturated hydrocarbon is known as alkane having general molecular formula CnH2n+2 .

The compounds in which series of atoms are connected to form a ring is known as cyclic compound whereas the compounds which are open chain compounds and their atoms doesn't form a ring is known as acyclic compounds. The general molecular formula of cyclic alkane is CnH2n .

Rules of drawing structures of cycloalkanes are:

  1. First identify the base name, and then draw the cyclic ring of carbon atoms according to the base name.
  2. After that according to the given position of the substituents, locate them on carbon atoms (replacement of hydrogen atom occurs).

(b)

Interpretation Introduction

Interpretation:

The structural formula of 2-Methyl-2-butene should be drawn.

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Unsaturated hydrocarbon having one or more double bond is known as alkene having general molecular formula CnH2n .

Rules of drawing structures of alkenes are:

  1. First identify the base name, and then draw the straight chain of carbon atoms according to the base name.
  2. After that according to the given position of the substituents, locate them on carbon atoms (replacement of hydrogen atom occurs).

(c)

Interpretation Introduction

Interpretation:

The structural formula of 2-Methyl-1,3-butadiene should be drawn.

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Unsaturated hydrocarbon having one or more double bond is known as alkene having general molecular formula CnH2n .

Rules of drawing structures of alkanes are:

  1. First identify the base name, and then draw the straight chain of carbon atoms according to the base name.
  2. After that according to the given position of the substituents, locate them on carbon atoms (replacement of hydrogen atom occurs).

(f)

Interpretation Introduction

Interpretation:

The structural formula of Cyclooctene should be drawn.

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Unsaturated hydrocarbon with one or more double bond is known as alkene having general molecular formula CnH2n .

The compounds in which series of atoms are connected to form a ring is known as cyclic compound whereas the compounds which are open chain compounds and their atoms doesn't form a ring is known as acyclic compounds. The general molecular formula of cyclic alkene is CnH2nm .

Where, m represents number of double bonds.

Rules of drawing structures of cycloalkenes are:

  1. First identify the base name, and then draw the cyclic ring of carbon atoms according to the base name.
  2. After that according to the given position of the substituents, locate them on carbon atoms (replacement of hydrogen atom occurs).

(g)
