Question

What type(s) of intermolecular forces are expected between ch3ch2ch2ch2oh molecules?

Answer 1

Answer:

1. Hydrogen bonding

2. Dipole dipole interaction

3. London dispersion force

Explanation:

Intermolecular forces refers to the force of attraction or force of repulsion between two molecules of same or other type.

In this case three types of Intermolecular forces acting:

1. Hydrogen bonding between O and H atom of different molecules.

2. Dipole dipole interaction between C and O atom because of great electronegative difference.

3. London dispersion force it is between two $-CH_3$ group of different molecules. It is also known as induced dipole force.

Hence, this is the required solution.  

Answer 2

Answer : Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

Explanation :

The given molecule is $CH_3CH_2CH_2CH_2OH$.

Three types of inter-molecular forces are present in this molecule which are Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

• Hydrogen-bonding : when the partial positive end of hydrogen is bonded with the partial negative end of another molecule like, oxygen, nitrogen, etc.

• Dipole-dipole attraction : When the partial positively charged part of the molecule is interact with the partial negatively charged part of the molecule. For example : In case of HCl.

• London-dispersion force : This force is present in all type of molecule whether it is a polar or non-polar, ionic or covalent. For example : In case of Br-Br , F-F, etc

Hydrogen-bonding is present between the oxygen and hydrogen molecule.

Dipole-dipole forces is present between the carbon and oxygen molecule.

London-dispersion forces is present between the carbon and carbon molecule.
