Acetylene (C2H2) has a triple bond between the two carbons. So 3 pairs of electrons. Biomed is talking about ethylene (C2H4).
Answer:
b) The solar radiation can be absorbed by clouds and the atmosphere
Explanation:
The clouds consist of water vapour and the atmosphere consists of mixture of ai for example the carbon dioxide and methane. The water vapour and these two gases can all absorb sunlight. Reason for this is that the bonding pairs of electrons come from different atoms in the molecule and the bonds are distorted. Symmetrical molecules but with distorted bonds or bond electron pairs.
