An unknown Compound D (molecular formula: C6H5NO) forms a silver mirror in a Tollens test and is soluble in aqueous HCl. The IR spectrum of Compound D displays several absorption peaks including peaks at 3070 cm-1 and 1700 cm-1 . 1H NMR data for Compound D as follows: Compound A: 9.7 ppm (singlet, 1H), 8.2 ppm (doublet, 2H), 7.5 ppm (doublet, 2H) Propose a structure for Compound D. Explain your answer using all of the information given. For the 1H NMR spectrum, be sure to label your compound to clearly outline all information for your peak assignments.

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

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.
