[Review Toples) In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35 °C, primary, secondary, and tertiary C-H bonds
react at relative rates of 1:3.9: 5.2 respectively.
These are conditions of kinetic control where product ratios are determined by relative rates of formation. For example, if A is formed twice as fast as B, the A:B
product ratio will be 2.
Consider chlorination of the alkane below at 35 °C.
1. Specify the most reactive C-H bond(s), a-c.
Two non-equivalent C-H bonds of comparable reactivity should be separated by commas, i. e. a, c.
2. Specify the site of chlorination in the major monochldro substitution product, a-c.
Two products that form in comparable quantities should be separated by commas, i. e. a, c

a. they must be certified by the avma.

explanation:

mark brainliest and have a great day!

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
