Explanation

The general formula for alkynes is:  

CₙH₂ₙ₋₂  

(Where n = number of carbon atoms)

Explanation

 The functional group present in aldehydes is the aldehyde group, which is represented as -CHO.

This group consists of a carbonyl group (C=O) where the carbon atom is bonded to at least one hydrogen atom. 

Explanation

The functional group -COOH is the carboxyl group, which is a characteristic functional group of carboxylic acids.

Carboxylic acids are a class of organic compounds that contain this group, examples include:

• Formic acid (HCOOH)
• Acetic acid (CH3COOH)
• Citric acid (C6H8O7)

Explanation

Explanation

HClO (hypochlorous acid) is the weakest acid among the given options.

The acidity of oxyacids of chlorine increases with the number of oxygen atoms bonded to chlorine.

Explanation

Kinetic Theory of Gases:

This theory explains that gases consist of a large number of tiny particles in constant, random motion.

The particles are far apart, move freely, and collide with each other and the container walls, which creates pressure.

Explanation

Allotropes of carbon include diamond, graphite, fullerenes (such as buckminsterfullerenes or «buckyballs»), and carbon nanotubes.

Other allotropes also exist, such as graphene (single sheets of graphite), amorphous carbon, and carbyne.

These forms differ in the arrangement of their carbon atoms and, consequently, have distinct physical and chemical properties. 

Explanation

The main intermolecular force in NH₃ (ammonia) is hydrogen bonding.

This strongest type of intermolecular force that occurs

Because the hydrogen atoms in ammonia are bonded to the highly electronegative nitrogen atom,

Creating strong partial negative and positive charges that attract the hydrogen of one NH₃ molecule to the nitrogen of another. 

Explanation

A solid with a definite shape and volume is known as a Crystalline solid has a regular,

A repeating arrangement of particles that gives it a definite geometric form and a sharp melting point.

An Amorphous solid lacks this long-range order and does not have a fixed shape or geometric form.

A Liquid has a definite volume but takes the shape of its container,

A Plasma is an ionized gas with no definite shape or volume. 

Explanation

Diffusion is fastest in gases because gas particles are far apart and scurry, allowing them to spread out and mix quickly.

In contrast, particles in liquids move more slowly, and solids have tightly packed particles, making diffusion much slower.
