(a) Regardless of the formal charge, apply octet rule to suggest four (04) possible Lewis structures of C3H6O (b) Use formal charge to determine the most plausible Lewis structures of C3H6O
(c) Predict the approximate values for bond angles of C3H6O
(d) Use box diagram to present the hybrid orbital of H, Cl and O in C3H6O
(e) Indicate electrons that form s and p bonds in the hybrid orbital diagram of each element on in H3H6O

1. they vary with a higher number because boiling is way hotter than melting

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.

there is none because earth is stationary and flat.
