A Level Chemistry 2017 Paper 1 Question 3 Solution
In this video we want to discuss 2017 A Level H2 Chemistry Paper 1 Question 3.
Let's take a look at this question.
Topic tested is on Chemical Bonding, in particular how to determine the Shape and Bond Angle of Molecules.
Valence Shell Electron Pair Repulsion (VSEPR) Theory is used to determine the shapes of simple molecules.
For this question the molecule given is methanal where the carbon is our central atom.
Number of bond pairs around carbon is 3 with no lone pairs.
So methanal has the basic shape of trigonal planar and the bond angle is 120o.
Therefore the answer to this question is D.
