Explanation

In molten NaCl, the ionic lattice breaks down.

Na⁺ and Cl⁻ ions become free to move, allowing electric conduction.

Explanation

Hydrocarbons are organic compounds composed only of carbon and hydrogen atoms.

Examples: Methane (CH₄), Ethylene (C₂H₄), Acetylene (C₂H₂).

Explanation

Aliphatic compounds are open-chain organic compounds (straight or branched chains).

They include alkanes, alkenes, and alkynes.

Explanation

Given:

Volume of CO₂ = 1.12 liters

At STP, 1 mole of any gas occupies 22.4 liters.

Molar mass of CO₂ = 44 g/mol

Let's find the number of moles:

moles = volume / 22.4 L/mol

moles = 1.12 L / 22.4 L/mol

moles = 0.05 mol

Weight = moles × molar mass

Weight = 0.05 mol × 44 g/mol

Weight = 2.2 g

Explanation

A Gooch crucible is used to filter precipitates or suspensions, such as potassium permanganate (KMnO₄) solutions.

It is made of porous material (e.g., asbestos or glass fiber) for fine filtration.

Explanation

A double bond (C=C) indicates that the compound is unsaturated.

Unsaturated compounds can add more atoms (e.g., hydrogen) across the double bond.

Explanation

Benzene (C₆H₆) has a planar hexagonal ring structure.

It consists of six carbon atoms with alternating single and double bonds (resonance structure).

Explanation

Chloroform (CHCl₃) on warming with silver powder undergoes coupling reaction to form C₂Cl₆ (hexachloroethane).

Reaction:

2CHCl3 → C2Cl6 + H2

Explanation

Alkyl halides react with lithium dialkyl copper reagents (Gilman reagents) in a nucleophilic substitution reaction.

The halide is replaced by the alkyl group, forming alkanes.

Explanation

Pancreatic juice, produced by the pancreas, contains a mix of enzymes that break down:

• Proteins (pepsin, trypsin, and chymotrypsin)
• Fats (lipase)
• Carbohydrates (amylase)
