Which of the following is an organic molecule
a) oxygen gas
b) sucrose
c) iron oxide
d) water

Option B - Sucrose

Explanation: Any compound containing carbon atoms covalently bound to other atoms is referred to as an ORGANIC COMPOUND or MOLECULE.

From the options provided, Oxygen gas (O2) does not have any carbon atom, so it is not an organic molecule; so also iron oxide (Fe2O3) and water (H2O).

Sucrose, however, with formula C12H22O11, consists of 12 carbon atoms bound to 22 hydrogen atoms, and 11 oxygen atoms.

So, Sucrose is the right answer.

it is prolly d and c and f

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
