What is the predominant intermolecular force in the liquid state of each of these compounds: water (H2O), methane (CH4), and dichloromethane (CH2Cl2)

el agua

Explanation:

La fuerza intermolecular más fuerte en el agua es un enlace dipolo especial llamado enlace de hidrógeno. muchas moléculas son polares y pueden formar enlaces bipolo-bipolo sin formar enlaces de hidrógeno o incluso tener hidrógeno en su molécula. el agua es polar, y el enlace dipolo que forma es un enlace de hidrógeno basado en los dos átomos de hidrógeno en la molécula.

- 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
