Using iupac nomenclature, give the name of bh3 and alh3 and elaborate why that name is correct. a) boron trihydride & aluminum trihydride - both molecules combine two non-metals and form covalent bonds. b) boron hydride & aluminum hydride - both compounds combine a main group metal and a non-metal to form ionic bonds. c) boron trihydride - boron and hydrogen are both non-metals and form covalent bonds. aluminum hydride - aluminum is a main group metal and hydrogen is a non-metal and they form ionic bonds. d) boron hydride - boron is a main group metal and hydrogen is a non-metal and they form ionic bonds. aluminum trihydride - aluminum and hydrogen are both non-metals and form covalent bonds.

The correct answer is Option C.

Explanation:

The nomenclature of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.

3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..

So, the IUPAC name for is boron trihydride.

The nomenclature of ionic compounds is given by:

1. Positive is written first.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

Hence, the name of is aluminium hydride.

Therefore, the correct answer is Option C.
