Which statement about 2‑methyl‑1‑propanol, (ch3)2chch2oh , and 1,3‑propanediol, hoch2ch2ch2oh is true? 2‑methyl‑1‑propanol is more soluble in water than 1,3‑propanediol because 2‑methyl‑1‑propanol has a smaller molecular mass. 2‑methyl‑1‑propanol is more soluble in water than 1,3‑propanediol because 2‑methyl‑1‑propanol forms fewer hydrogen bonds with water. 1,3‑propanediol is more soluble in water than 2‑methyl‑1‑propanol because 1,3‑propanediol has a smaller molecular mass. 1,3‑propanediol is more soluble in water than 2‑methyl‑1‑propanol because 1,3‑propanediol can form multiple hydrogen bonds with water.

Propane-1,3-diol is more soluble in water than 2-methylpropan-1-ol because propane-1,3-diol can form more hydrogen bonds with water.

Explanation:

The structures of the two compounds are shown below.

The two compounds have almost the same molecular mass (72 vs 74), so the important factor must be the number of OH groups.

Thus, propane-1,3-diol is more soluble in water than 2 methyl 1 propanol because propane-1,3-diol can form more hydrogen bonds with water.

A and C are wrong. The molecular masses of the two compounds are almost identical.

B is wrong. Fewer hydrogen bonds would make 2-methylpropan-1-ol less soluble.

its mg hope this

- 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
