Which one violates the octet rule?
Andrews [41]

Answer:

F1+ is the one that violates the octet rule

goldenfox [79]

The homologous series ( not homogeneous series ) of n-propyl bromide is C3H7Br. It is also known as 1-Bromopropane

n-propyl bromide or 1-bromopropane, is a solvent that is used in cleaning metals, vapor degreasing and also for dry cleaning.

<h3>What is Homologous series?</h3>

Homologous series is a family of organic compound which follows a regular structural pattern and in which successive members differs from one another by a molecular formula of CH2

Below are some of their characteristics:

  • The general formula of all compounds in the series is the same.
  • They have the same functional group.
  • Their physical properties such as melting point, boiling point, density, generally show a gradual change with increase of molecular formula in the series.
