Question

1. Identify the set of oxides that consist of an acidic, basic, a neutral and an amphoteric oxide respectively a. SO3 , CaO, H2O, Al3O3 b. SO3, MgO, NO, Na2O c. N2O, K2O, H2O, ZnO d. CO2, CO, SO2, Al2O 2. Reactions of alkene are mostly a. Elimination reactions b. Subtraction reaction c. Substitution reaction d. Addition reaction 3. The thermal stability of alkaline earth metal nitrate is in the order Mg(NO3)2

Answer 1

1. Option A

2. Option D

Step-by-step explanation:

1. Acidic oxides are those that produces acid on reacting with water and are mostly made up of non-metals. For example - SO2, CO2, SO3, Cl2O7, P2O5, N2O5 etc

Basic oxides are those which produces base on reacting with water and are mostly made up of metals such as Na2O, CaO, BaO

Neutral oxides do not form salts on reacting with acid or bases. For example H2O

Amphoteric Oxide are the one that display dual behaviour for example – ZnO, Al2O3

Hence, option A is correct

2. Most of the alkene reactions are addition reactions in which two or more alkene molecules add to produce large compounds. Hence, option D is correct
