The electron cloud model uses the basic idea of Bohr's model, representing the atom as if it were cut in half. The difference is that Bohr's model showed electrons in "shells" which modeled that they moved only in a distinct orbit around the nucleus. The modern model has layers of electrons, but models the concept that they form a cloud where their exact position is impossible to known (considering is changes). The modern model explains that electrons are not at a fixed distance from the nucleus, but the Bohr model does not represent this understanding, instead, it displays a concept that the electrons are at fixed levels of orbit.

Answer:

According to modern model of atom that is the electron cloud atom, the electrons are found in orbitals. Orbitals are the region where there is probability to find an electron in an atom. According to Bohr's model, electrons revolve around the nucleus in fixed energy shells.

Electron cloud model explains that the position of electron cannot be found exactly. It can be found in a region. The repeating nature of chemical properties of atoms in periodic table can be explained by both the models.

Give the structure of the principal organic product formed by free-radical bromination of 2,2,4−trimethylpentane.
Fudgin [204]

the principal organic product formed by free-radical bromination of 2,2,4−trimethylpentane is 2-bromo-2,4,4-trimethylpentane.

what is free radical halogenation?

A substitution reaction in which a hydrogen atom is replaced with a halogen atom, via a free radical reaction mechanism. when this reaction is carrid out by bromine radical, it is called free radicle bromination. When bromine (Br{2}) treated with light (hν) it comes to homolytic cleavage of the Br-Br bond and give rise to bromine radicles.

free-radical bromination of 2,2,4−trimethylpentane

Bromination of an alkane includes the substitution of a bromine atom for a hydrogen atom. The following stages will be taken by 2,2,4-trimethylpentane during this reaction:

Initiation reaction:  The production of a bromine free radical requires the initiation of heat or light.

Br - Br ⇒ 2Br·

Propagation: This reaction relies heavily on hydrogen. This reaction is impossible if hydrogen is not present. Because tertiary free radicals are more stable than secondary and primary free radicals, they are favoured in this reaction.

Termination: The remaining free radical of bromide reacts with the tertiary free radical of 2,2,4-trimethylpentane to form 2-bromo-2,4,4-trimethylpentane.

the principal organic product formed by free-radical bromination of 2,2,4−trimethylpentane is 2-bromo-2,4,4-trimethylpentane.
