In aldehydes and ketones, the electropositive carbon atomas has a much greater attraction for the bonding electron pairs than does the oxygen atom?

Explanation:

The carbon-to-oxygen double bond in the aldehydes is quite polar in nature. The oxygen atom which is electronegative  in nature has much greater attraction for bonding electron pairs than carbon atom.

Thus, carbon atom has partial positive charge while oxygen atom has partial negative charge.

Thus the the electropositive carbon atom has much greater attraction for bonding electron pairs than oxygen atom.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
