Oxygen because it is on the left of the periodic table so it has a strong pull.

Answer:

Oxygen atom will strongly attract the shared pair of electrons towards itself.

Explanation:

The bond formed between magnesium and oxygen atom is an ionic bond.In this type of chemical bond transfer of electrons takes place from one atom to another.

Electronegativity : tendency to attract shared purr of electrons towards itself.

The transfer of electrons from one atom to another type of an atom depends upon the electronegativities of the atoms.

Higher the electronegative character in an atom more will be the tendency of that atom to attract the electrons towards itself and form electronegative ion.
Lower the electronegative character ,more easily it will donate its electrons and form a electropositive ion.

Out of magnesium and oxygen, oxygen is a second most electronegative element in a periodic table which means it will easily attract the shared pairs of electrons towards it self.

What would be the major product obtained from hydroboration–oxidation of the following alkenes?

zmey [24]

Answer:

a. 3-methylbutan-2-ol

b. 2-methylcyclohexan-1-ol

Explanation:

For this reaction, we must remember that the hydroboration is an "anti-Markovnikov" reaction. This means that the "OH" will be added at the least substituted carbon of the double bond.

In the case of 2-methyl-2-butene, the double bond is between carbons 2 and 3. Carbon 2 has two bonds with two methyls and carbon 3 is attached to 1 carbon. Therefore the "OH" will be added to carbon three producing 3-methylbutan-2-ol.

For 1-methylcyclohexene, the double bond is between carbons 1 and 2. Carbon 1 is attached to two carbons (carbons 6 and 7) and carbon 2 is attached to one carbon (carbon 3). Therefore the "OH" will be added to carbon 2 producing 2-methylcyclohexan-1-ol.

The relatively high boiling point of water is due to water having

Verizon [17]

The answer should be hydrogen bonding. Water only has oxygen and hydrogen in it, which are both nonmetals, so you know the answer cannot be metallic or ionic. It also cannot be nonpolar because the electronegativity of the oxygens will make the molecule polar. You can also know it is hydrogen bonding because it can only take place when a hydrogen is attached to an oxygen, fluorine, or nitrogen. These bonds are very strong attractions, so the molecules are extremely hard to pull apart, creating a high boiling point. Hope that helps!

How do water molecules move away from their H-O-H configuration to become new molecules?

maksim [4K]

Answer:

A water molecule is consists of two hydrogen atom, each bound to the central oxygen atom through a covalent chemical bond.

Water molecules can form new molecules by moving away from their H-O-H configuration due to thermal motions and rotations. Thermal motions and rotations break the individual hydrogen bonds and change the H-O-H configuration influenced by the temperature and pressure.
