Which is a property of alkynes?

a) alkynes have a neutral ph.
b) alkynes tend to be acidic.
c) alkynes tend to be soluble in water.
d) alkynes are not combustible

The correct answer is option B.

Explanation:

In Alkynes carbon with triple bond has sp hybridization. Presence of 50 % of s-character makes these carbon atoms highly electronegative in nature due to which electron bond pair are strongly attracted towards the carbon and proton get easily released.

Hence, acidic in nature.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
