How do you determine what is least soluble in water? Water molecules and hexane molecules cannot mix readily, and thus hexane is insoluble in water. It is a colorless viscous liquid that is insoluble in water. 1-Decanol is a straight chain fatty alcohol with ten carbon atoms and the molecular formula CH3(CH2)9OH. The alcohol 1-decanol (CH 3CH 2CH 2CH 2CH 2CH 2CH 2CH 2CH 2CH 2OH) is essentially insoluble in water. Can 1-Decanol hydrogen bond with water?Īlcohols can also engage in hydrogen bonding with water molecules (Figure 14.3 “Hydrogen Bonding between Methanol Molecules and Water Molecules”). That is, the oxygen in the carbonyl group is more electronegative than the carbon. Why does acetone dissolve nonpolar?īecause acetone contains non-polar methyl groups, it has the ability to interact with non-polar substances such as certain organic compounds but because it has a polar carbonyl group, it works well with water, too. The molecules that compose acetone do have nonpolar covalent bonds within their overall structure, such as their carbon to hydrogen and carbon to carbon bonds. Does acetone have nonpolar bonds?Īcetone molecules are polar because of the positive and negative charges formed by their carbonyl group.
All of these bonds are polar (C-H only very slightly so). In CHCl3, the molecular shape is tetrahedral, meaning that the H and the three Cl atoms will occupy the vertices of a triangular based pyramid around the central C atom.
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).ġ Answer.
Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule. Therefore, the dipoles of the S-F bond do not cancel out each other and molecules turn out to be polar and contribute some dipole moment. SF2 is polar in nature because the sulfur(2.58) and fluorine(3.98) atoms in the molecule differ in their electronegativity and the molecule has a bent geometrical shape.
