Nucleophilic addition reactions:
While the addition reaction takes place on account of the initial attack of nucleophile, the reaction is known as a nucleophilic addition reaction. Due to existence of strongly electronegative oxygen atom, the p -electrons of the carbon-oxygen double bond in carbonyl group (C = O) obtain shifted towards the oxygen atom and thus such bond is highly polarised. This makes carbon molecules of the carbonyl group electron deficient.
The ratio of the energy of a photon of 2000Å wavelength radiation to that of 4000 Å radiation is: (1) 1/4 (2) 4 (3) 1/2 (4) 2 Ans

The amount of heat liberated when single mole of any substance is completely burnt in oxygen is known as heat of combustion H is negative for heat of combustion.
Q. Explain about Neutral and Amphoteric oxides? Neutral oxides have neither acidic nor basic properties and when dissolved in water, they give neutral solutions, e.g., CO, N
