Answer:

Option 3 - Grignard reagents are strong bases and option 4 - Grignard reagents are strong nucleophiles

Explanation:

The carbon in grignard reagent has a very strong carbanionic character which gives grignard reaction it's unique characteristic of a strong base and strong nucleophile.

Which Of These Is An Indication That A Chemical Reaction Has Occurred?
nikdorinn [45]

<u><em>Answer:</em></u>

Correct option is D. Formation Of A Gas

<u><em>Explanation</em></u>

The main indication of chemical is that new substances are formed which have different composition than reactant.

<u><em>Freezing of a substance: </em></u>As in this case composition remained  same, so we cant say, chemical reaction is take place, like when water freezes, it composition is same as water , so it is only its physical properties, not chemical.

<u><em>Melting of a substance:</em></u> As in this case composition remained same, so we cant say, chemical reaction is take place, like when ice melts, composition of water remained same , so it its physical properties, not chemical.

<u><em>Boiling of a substance:</em></u> As in this case composition remained same, so we cant say, chemical reaction is take place, like when water boils and become vapors, composition of water and vapors remained same , so it its physical properties, not chemical properties which show its chemical reaction.

<u><em>Formation of gas:</em></u>

In this case, chemical reaction take place. In chemical reactions, new substance are formed whose composition is different from reactants.
