If you're looking for the definition it is
The most common definition of energy is the work that a certain force can do. Energy also cannot be created or destroyed and some examples are
light, heat, mechanical, potential, and kinetic
The elements Carbon, Hydrogen, and Oxygen are all part of Non-Metals.

Correct Answer: CH2CCI2 and CH2CH2.
Reason:
Structure of compound depends on the hybridization of central atom. In both of the above molecules (i.e. CH2CCL2 and CH2CH2). Central atom i.e. carbon is
sp^2 hybridized. Thus 3 hybridized orbitals of 'C' is involved in sigma bonding. Further, these orbitals are placed spatially at an angle of

. The un-hybridized 2pz orbital of 'C' is involved in pi-bonding. Due to this, both of the above molecules possess a
triangular planner geometry.
