What is the percentage of s-character in an sp hybrid? O 25% 50% o 75% O 66%

marishachu [46]

Answer: 50%

Explanation:

The number of electron pairs are 2 for hybridization to be $sp$ and the electronic geometry of the molecule will be linear.

1. percentage of s character in sp hybrid orbital = $\frac{\text {number of s orbitals}}{\text {total number of orbitals}}=\frac{1}{2}\times 100=50\%$

2. percentage of s character in $sp^2$ hybrid orbital = $\frac{\text {number of s orbitals}}{\text {total number of orbitals}}=\frac{1}{3}\times 100=33.3\%$

3. percentage of s character in $sp^3$ hybrid orbital = $\frac{\text {number of s orbitals}}{\text {total number of orbitals}}=\frac{1}{4}\times 100=25\%$

Thus percentage of s-character in an sp hybrid is 50%.

Anvisha [2.4K]

Answer:Ionic compounds form when positive and negative ions share electrons and form an ionic bond. ... The positive ion, called a cation, is listed first in an ionic compound formula, followed by the negative ion, called an anion. A balanced formula has a neutral electrical charge or net charge of zero.

Explanation:Simple ions:

Perchlorate ClO4- IO3-

Chlorate ClO3- BrO3-

Chlorite ClO2-

Answer:

A. PO43-

Explanation:

in the given is buffer . so H2PO4- and HPO42- both are present with equal concentration . Na+ is spectator ion it is also present in the concentration higher than the given species above .

but PO4-3 is not present . so it is lowest concentration
