Answer: Option (C) is the correct answer.

Explanation:

A covalent compound is formed by sharing of electrons between two chemically combining atoms.

A covalent bond will always form between non-metals.

Some properties of covalent compounds are as follows.

  • Covalent compounds are brittle in nature. This means they tend to break easily.
  • Covalent compounds have low melting and boiling point.
  • These compounds are unable to conduct heat and electricity.
  • Covalent compounds generally do not dissolve in water.

As covalent compounds have low melting and boiling point so, it is possible that they evaporate at room temperature.

Thus, we can conclude that sample C is a liquid that evaporates at room temperature, most likely to be a covalent compound.

Answer:

( a ) Filtration

( b ) sugar refining .

Explanation:

( a ) Filtration

By the process of filtration pasta from water can be removed , as pasta is not soluble in water , hence , by filtration , the solid pasta will remain in the filtration funnel , and the water will flow down , thereby , removing pasta from the water .

There are four different starting molecules that one might use to synthesize the illustrated alkyl halide as the major product u
Mkey [24]

Answer:

Explanation:

An electrophilic addition reaction occurs when an electrophile attacks a substrate, with the end result being the inclusion of one or many comparatively straightforward molecules along with multiple bonds.

In the given question, the hydrogen bromide provides the electrophile while the bromide is the nucleophile. The mechanism proceeds with the attack of the electrophile on the carbon, followed by deprotonation. This process is continued with a formation of carbocation and the bromide(nucleophile) finally bonds to the carbocation to form a stable product.

The first diagram showcases the possible various starting molecules for the synthesis while the second diagram illustrates their mechanism.
