1 answer:

6 0

Here is the full question with choices: When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule, __________.?

A. the hydrogen atom becomes partially positive

B. the electronegative atom becomes strongly positive

C. the hydrogen atom becomes partially negative

D. the oxygen atom becomes partially negative

The answers are A and D. The oxygen holds onto the electrons more of the time so is slightly negative, making H slightly positive and thus making a polar covalent bond.

Identify what the electron dot diagram tells you about bonding

Alex_Xolod [135]

The electron dot diagram tells us about how many electrons are being shared between atoms. Also, the number of valence electron to be shared corresponds to the group number the element belongs. Say for example H2O, hydrogen has one valence electron and oxygen has two valence electrons.

Sulfonation of naphthalene, C10H8, results in two products. One product is kinetically favored and predominates in the beginning

Marrrta [24]

Explanation:

The sulfonation of the naphthalene yield 2 products under different conditions:

<u>When the reaction is carried at 80 °C, 1-naphthalenesulfonic acid is the major product because it is kinetically favoured product as arenium ion formed in the transition state corresponding to 1-naphthalenesulfonic acid is more stable due to better resonance stabilization. </u>

<u>When the reaction is carried at 160 °C, 2-naphthalenesulfonic acid is the major product as it is more stable than 1-naphthalenesulfonic acid because of steric interaction of the sulfonic acid group in 1-position and the hydrogen in 8-position.</u>

The products are shown in image below.
