Why the dipole moment of alkyl chloride is greater than alkyl fluoride?

Difference in EN is high for alkyl http://chloride.so it has high dipole moment. The atomic radius of fluorine is smaller than the atomic radius of Cl. Hence, the attraction from the protons is higher, accordingly the ionization potential is much lower.

Which halide has highest dipole moment?

CH3Cl
CH3Cl has higher dipole moment than CH3F due to much longer C-Cl bond length than the C-F bond. The much longer bond length of the C-C bond outweighs the effect produced by lower electronegativity of Cl than that of F.

Why alkyl halides are better solvent than aryl halides?

The C-X bond in alkyl halides are little polar and longer due to more elecronegativity of halogen atom, and so the carbon bears a little +ve charge while halogen-atom bears a little -ve charge. Hence, alkyl halides are better solvents than aryl halides.

Which out of ammonia and nitrogen trifluoride has more dipole moment and why?

Answer: N- atom is the central atom of NF3 and NH3. The Central atom is having 1 lone pair and is having 3 bond pairs. As, F-atom is more electronegativity than H- atom,NF3 should have higher dipole moment than NH3.

Why is dipole moment of HF higher than HCl?

Fluorine is more electronegative than chlorine. Hence dipole moment of HF is higher than HCl.

How do you determine the highest dipole moment?

The larger the difference in electronegativities of bonded atoms, the larger the dipole moment. For example, NaCl has the highest dipole moment because it has an ionic bond (i.e. highest charge separation).

Which one of the following is the highest dipole moment?

$C{{(Cl)}_{4}}$ is a symmetrical compound so its dipole moment will be zero. Hence, $C{{(Cl)}_{4}}$ is non-polar. Hence, $C{{(H)}_{2}}{{(Cl)}_{2}}$ has the highest dipole moment amongst the given options. Hence, B is the right answer.

Why boiling point of alkyl bromide is higher than alkyl chloride?

Answer: Boiling point of alkyl bromide is higher than alkyl chloride because as the size of the halogen atom increases magnitude of van der waals force increases.

Why do alkyl halides show nucleophilic substitution reaction?

In case of alkyl halides, the halogen atom due to its -I effect pulls electrons from the carbon chain and hence it acquires a partial positive charge and so gives nucleophilic substitution reactions.

What is the difference between alkyl and aryl groups?

Alkyl and aryl are two chemical terms used to name functional groups of organic compounds. The main difference between alkyl and aryl is that alkyl group has no aromatic ring whereas aryl group has an aromatic ring.

What is the Order of bond strength of alkyl halide?

order of bond strength (bond energy): C-F > C-Cl > C-Br > C-I. ii) The sp3 C-X bonds of alkyl halides are longer than sp2 C-X bonds of vinyl and aryl halides. In the latter case, the C-X bond has partial double bond character that arises due to delocalization of π electrons.

What is the structure of aryl halide?

An aryl halide is a molecule having a halogen atom attached to a sp2 hybridized carbon in an aromatic ring directly. This is an unsaturated structure due to the presence of double bonds in the aromatic ring. Aryl halides also show the dipole-dipole interactions.

Why do MPs of alkyl and aryl halides increase with increase in molecular weight?

The MPs and BPs of alkyl and aryl halides increase with increase in the molecular size or molecular weight. The main reason is strengthening of dispersion forces rather than permanent dipole-dipole interactions. It is clearly evident from the melting and boiling points of methyl halides.

How do the C-X bonds of vinyl and aryl halides differ?

The C-X bond weakens with increase in the bond length and decrease in the overlap of atomic orbitals. ii) The sp 3 C-X bonds of alkyl halides are longer than sp 2 C-X bonds of vinyl and aryl halides.
