Which is an application of the trimethylsilyl (TMS) group in organic synthesis?

Protecting group

Explanation:

TMS groups can be used as protecting and leaving groups for the synthesis of siloxane-based molecules.   It is also used as protecting group for alcohols.

A protecting group is a temporary group added during organic synthesis to prevent a portion of molecule from reacting.

im not exactly sure but i think its b!

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
