HF (hydrogen fluoride) becomes a gas at a higher temperature than does HCl (hydrogen chloride). This is inconsistent with the trend where the boiling point increases when moving down a group on the periodic table.
Explain the reason for this inconsistent behavior.
A)
the hydrogen bonds present in HF
B)
the hydrogen bonds present in HCL
the electropositive nature of fluorine
D)
the higher electronegativity of chlorine

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
