Consider the two Lewis structures given below: Lewis representation of BCl3 Lewis representation of NH3 Which of the following statements is correct? Structure 2 can be classified as both a Brønsted–Lowry and a Lewis base. In a reaction, structure 1 would function as a Lewis base while structure 2 would function as a Lewis acid. Structure 2 would have similar Lewis acid–base properties as those of AlCl3. Structure 1 can be classified as both a Brønsted–Lowry and a Lewis aci

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the answer is either b or c

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
