Identify the bond with the highest bond energy. identify the bond with the highest bond energy. c=c si=o c=n n=n o=o

The bond with the highest bond energy is C=C bond, with the energy of 620 kJ/mol.

Explanation:

Bond energy can be defined as the bond strength of the chemical bond.

The bond energy can be associated with the electronegativity of the atoms. The more electronegative atom, the more will be the bond energies.

The bond energies of the same bonded atoms are higher than the bond with two different atoms.

The bond energy of C=C : 620 kJ/mol

Si=O : 452 kJ/mol

C=N : 615 kJ/mol

N=N :  418 kJ/mol

O=O : 498 kJ/mol

The C=C bond has the highest bond energy.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
