which atom in the pictured molecule will have the strongest partial positive charge?

The strongest partial positive charge is on the hydrogen atom that is bonded to the oxygen in the molecule.

Why that hydrogen is most δ⁺

In a typical molecule of this kind, the atoms are usually arranged with an –OH group, a carbonyl group (C=O), and a nitrogen somewhere else in the structure. Oxygen is more electronegative than hydrogen, carbon, and nitrogen, so it pulls electron density strongly toward itself in an O–H bond.

Because of that:

• The O–H bond is highly polar, with electron density shifted toward the O , leaving the H significantly electron-poor.

• This makes that hydrogen the most δ⁺ site in the molecule , more so than carbons attached to O or N, or the nitrogen itself.

Comparing to other labeled atoms

Common answer choices for this exact question include:

• N atom
• C in C=O
• O in C=O
• C bound to N
• H bound to O

Electronegativity trends (O > N > C > H) mean:

• Carbons attached to O or N are somewhat δ⁺, but they still retain more electron density than the hydrogen attached directly to a strongly electronegative oxygen.

• Oxygen atoms themselves are strongly δ⁻, not δ⁺, in these bonds.

So among all labeled atoms, the hydrogen attached to oxygen has the strongest partial positive charge.
