in which of the following substances, weakest inter molecular force is expected: H2O, CH3OH
Answers
Answer:
Explanation:
CH3OH
Answer:
A specific type of dipole-dipole interaction is hydrogen bonding. It can only happen when the molecules in concern have an atom that is extremely electronegative immediately connected to a hydrogen atom, creating an extreme dipole that is out of the usual.
Explanation:
Due to strong hydrogen bonds between its own molecules and those of its neighbors, water (H₂O) has a greater intermolecular force than methanol.
Water has a greater boiling point than methanol because of this hydrogen bonding.
Since methanol (CH₃OH) contains a carbon atom, hydrogen bonds cannot form in this substance. it further provides steric hindrance.
Only nitrogen, oxygen, and fluorine are considered to be these extremely electronegative elements for the majority of applications.
A "donor" and an "acceptor" molecule form a hydrogen bond. The acceptor supplies the electronegative atom for the bond while the donor supplies the hydrogen atom.
Hence, the weakest intermolecular force is expected in CH₃OH.
