The H NMR spectrum of a compound with formula C7H14O shows only two signals. Which of these structures is a possible one for this compound?a. 2-Heptanoneb. 3-Heptanonec. 4-Heptanoned. 2,4-Dimethylpentan-3-onee. 2,2-Dimethylpenta-3-onef. None of the above

sry but any answer choices

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.
