Determine if each of the following statements about chiral molecules is True or False and select the best answer from the dropdown menus. All R stereocenters are dextrorotatory. Chiral centers in organic molecules will have 4 different groups attached to a carbon. A racemic mixture has an optical activity of 0. Normal linear amines can be chiral centers. Compound C has an optical activity of 0. If the R isomer of a molecule has an optical rotation of 25.7o then the S isomer of the molecule will have an optical rotation of -25.7o. A CN is higher priority than a CH2OH. All molecules with c

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.
