Synthesis | MCQs

Explanation

Water gas is a mixture of Carbon Monoxide (CO) and Hydrogen (H2).

Water Gas is formed when steam is passed over red-hot coke.

Formula: H₂O

Boiling point: 100°C

Explanation

Explanation

Explanation

• Hydrogen and Oxygen combining to form water, which is an example of a synthesis reaction: 2H2 + O2 → 2H2O
• In this reaction, two substances (hydrogen and oxygen) combine to form a new compound (water).

Explanation

• An Addition Reaction is a type of chemical reaction where two or more substances combine to form a new, single compound.
• This type of reaction involves the formation of a new chemical bond, resulting in a single product with a unique identity.

Explanation

Acetic acid can be prepared by the hydrolysis of: Methyl cyanide
(Methyl cyanide, also known as acetonitrile, upon hydrolysis yields acetic acid.)

Explanation

Acetamide, which is a primary amide and has the chemical formula CH3CONH2, is typically prepared by heating ammonium acetate.

Here's the reaction:

CH3COO −NH4+ → CH3CONH2 + H2O

In this reaction, ammonium acetate (CH3COONH4) decomposes upon heating to form acetamide (CH3CONH2) and water (H2O).

This process is a type of thermal decomposition reaction.

Explanation

Basic lead chromate is formed when lead chromate (PbCrO4) is boiled with dilute alkali hydroxide.

Here's the reaction:

PbCrO4 +OH- → PbO⋅PbCrO4 +H2O

In this process, the lead chromate reacts with the dilute alkali hydroxide to form basic lead chromate.

The alkali hydroxide used is typically a dilute solution of sodium hydroxide (NaOH) or potassium hydroxide (KOH).
