Answer:

See the explanation.

Explanation:

$CH_{4 } + O_{2} ------> CO_{2} + 2H_{2 } O$

Hydrocarbons on combustion give carbon dioxide and water.

Hydrocarbons contain all kinds of saturated and unsaturated ones.

Alkanes on reaction with oxygen gives carbon dioxide and water.

Alkenes on reaction with oxygen gives carbon dioxide and water.

Alkynes on reaction with oxygen gives carbon dioxide and water.

The water lattice: a. is formed from hydrophobic bonds. b. causes ice to be denser than water. c. causes water to have a relativ

Alexus [3.1K]

Answer: Option (d) is the correct answer.

Explanation:

It is known that water loving bonds are called hydrophilic bonds and water hating bonds are called hydrophobic bonds. Since, water is a polar solvent and it is only able to dissolve polar molecules and not non-polar molecules.

Lattice of water and hydrogen bonding are responsible for the various properties of water like cohesion, adhesion, heat of vaporization etc.

Thus, we can conclude that water lattice excludes non-polar substances.
