Which general formula represents the functional group in a carboxylic acid? roh rcoor rcooh rcho

Answer : The correct option is, RCOOH

Explanation :

A carboxylic acid is a class of an organic compound which contain a functional group with (-COOH) i.e R-COOH (R is an alkyl group)

In R-COOH functional group, a carbon atom is bonded to an oxygen atom with double bond and a hydroxyl group with single bond. And the fourth bond links the carbon atom to an alkyl group, (R) or a hydrogen atom.

Examples of carboxylic acids are ethanoic acid,, propanoic acid,

Therefore, the correct answer is, RCOOH

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
