Explanation

The one-step mechanism is known as the E2 reaction,

and the two-step mechanism is known as the E1 reaction.

Explanation

The dry distillation of fused calcium acetate gives acetone as the main product.

Dry distillation of calcium salts of carboxylic acids gives aldehydes or ketones.

When calcium acetate ((CH3COO)2Ca) is heated, acetone (CH3−CO−CH3) and calcium carbonate (CaCO3) are obtained.

Explanation

Explanation

acetone reacts with iodine to form iodoform in the presence of NaOH.

Explanation

Ether is formed when ethyl alcohol is heated with conc. H2 ...

When excess ethanol is heated with sulphuric acid at a temperature of 413K (1400C) we get Diethyl ether.

Explanation

Among suitable choices, certainly, ethanol dehydrogenation to acetaldehyde is desirable CH3CH2OH(g) → CH3CHO(g) + H2(g) ΔH0298 = 68.6 kJ/mol.

This reaction is endothermic and characterized by a reaction enthalpy variation of 68.6 kJ/mol. (Leblud et al., 1981)
