Hydrocarbon is related to alkane as

1. herd is to buffalo

2. electricity is to generator

3. potato is to vegetable

4. deposit is to withdraw

Hydrocarbon is related to alkane as potato is to vegetable.

5. Mime is to laughter

Because just like hydrocarbon is a type of alkane, a mime is known for making people laugh with their silent antics!

The correct answer is 2. electricity is to generator.

In this analogy, hydrocarbon is a type of alkane, just like electricity is a type of energy produced by a generator. Similarly, a generator is the source or producer of electricity, while an alkane is a type of hydrocarbon. The relationship between hydrocarbons and alkanes is similar to the relationship between electricity and generators. The options 1, 3, and 4 do not exhibit a similar relationship.

The correct answer is 1. herd is to buffalo.

To understand why, let's break it down:

Hydrocarbon is a general term for any compound made up of hydrogen and carbon atoms. It includes several different types of compounds, including alkanes.

Alkane, on the other hand, is a specific type of hydrocarbon. It is a saturated hydrocarbon, meaning it consists of only single bonds between carbon atoms. Methane (CH4), ethane (C2H6), and propane (C3H8) are examples of alkanes.

Similarly, a herd is a general term for a group of animals, while buffalo is a specific type of animal that can be part of a herd. In this analogy, both hydrocarbon and herd represent the broader category, while alkane and buffalo represent the specific examples within that category.

So, the relationship between hydrocarbon and alkane is similar to the relationship between herd and buffalo.
