How many lone pairs does the hydrogen molecule contain h2?

Chemistry

SVEN [57.7K]3 years ago
6 0

Answer:

None

Explanation:

Lone pairs of electrons are a set of 2 electrons pair which are not involved in bonding but are present in the outermost shell of the electron.

To accurately get them, we can primarily use the Lewis dot formula. After drawing our bonds, we can still some pairs of electrons which are nonbonding but are present.

Hydrogen atom has one electron. To form the hydrogen gas molecule, each hydrogen atom donates an electron each for sharing via covalent bonding, hence both electrons are used for bonding and we do not have any extra electrons.

In an experiment, two unknown compounds (one an alcohol and the other an ether) of equal molecular mass were dissolved in water.
-BARSIC- [3]

Answer: B. It is an ether because it is unable to to form a hydrogen bond, so it is less soluble than water

Explanation: Alcohols (ROH) are more soluble in water as they can form hydrogen bonding with water whereas ethers (ROR) are less soluble as they do not form hydrogen bonds with water.

For formation of hydrogen bond, the electronegative atom (F, Oand N) must be attached to hydrogen and in ethers (ROR), there is no hydrogen directly attached to electronegative oxygen atom, thus are less soluble in water.
