What organic products would be formed from the reaction of 1-bromo-2-methylpropane (isobutyl bromide), (ch3)2chch2br, with ch3o-, ch3oh?

Primary alkyl halide are those in which halogen is attached to that carbon which is attached to only one other carbon. Primary alkyl halides usually undergo (bimolecular nucleophilic substitution) mechanism (in which nucleophiles attack from the backward direction) and rarely  (bimolecular elimination) mechanisms.

1-bromo-2-methylpropane (isobutyl bromide), is a primary alkyl halide which on reacting with strong base, both products are formed from and mechanism. As methoxide ion is a good nucleophile formed from the strong base methanol. The reaction is shown in the image.

The products formed are 1-methoxy-2-methylpropane (from mechanism) and 2-methylpropene (from mechanism).

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
