Answer: The correct answer is Option 2.

Explanation:

Hydrocarbons are defined as the compounds which have a covalent bond present between hydrogen and carbon atoms. For Example: $CH_4$ is a hydrocarbon. $H_2O,CO_2$ are not considered as hydrocarbons.

For the given options:

Option 1: butanal

The chemical formula for this compound is $CH_3CH_2CH_2CHO$

This is not considered as a hydrocarbon because a covalent bond is present between carbon and oxygen atom.

Option 2: butyne

The chemical formula for this compound is $CH\equiv CCH_2CH_3$

This is considered as a hydrocarbon because covalent bonds are present between carbon and hydrogen atoms only.

Option 3: 2-butanol

The chemical formula for this compound is $CH_3CH(OH)-CH_2CH_3$

This is not considered as a hydrocarbon because a covalent bond is present between carbon and oxygen atom.

Option 4: 2-butanone

The chemical formula for this compound is $CH_3C(O)-CH_2CH_3$

This is not considered as a hydrocarbon because a covalent bond is present between carbon and oxygen atom.

From the above information, the correct answer is Option 2.

The point on a magnet Where magnet effect is strongest is called

notsponge [240]

Pole

Explanation:

A magnetic pole is the point on a magnet where a magnet effect is strongest. Around a magnet, there are magnetic fields.

The magnetic fields are force fields that leaves the north poles and enters through the south.
The pole is where magnetic effects are the strongest.
It is around the pole that the strongest magnetic effect on a magnet or magnetic material is felt.
The strength of magnetic fields are strongest at the poles.

Which of the following statements is true about the specific heat capacity of a substance?

Ludmilka [50]

Answer:

Option A

Explanation:

An intensive property is a bulk property, meaning that it is a local physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties include temperature, T; refractive index, n; density, ρ; and hardness of an object,specific heat, η.

Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, specific heat and many others.

Answer:

A mixture has more than one things that are not fused chemically

Explanation:

Mixture comprises two or three compounds that aren't fused chemically. They have no physical interactions. A solution contains two substances that are chemically mixed to form a new compound. The chemical properties of each substances are retained without change.
