Carbonyl Compounds containing
alpha proton readily donates alpha acidic proton when treated with
strong Base. In given statement <span>
2-phenylacetaldehyde is converted into Enolate and Enolates acts as a nucleophile and attacks carbonyl group of
Benzaldehyde. The mechanism of given reaction is as follow, the movement of electrons is shown by

A molecular formula represents the exact number of atoms present for each element in the compound.
For carbon atom: = ( as molar mass of carbon is 12 g/mol)
Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6
Thus, formula becomes (
Now, check for unsaturation:
Degree of unsaturation =
Substitute the value of x and y,
Degree of unsaturation =
=
= implies one ring and three double bonds.
Thus, formula comes out to be i.e. benzene ring.
<span>Hazards from huge explosive eruptions comprise extensive ash-falls with small glass particles in it, pyroclastic flows (combinations of hot gases and pumice chunks), and immense lahars which are volcanic mud flows which can even include debris. These put people within the area in danger. Nearby properties get damaged as well within a circumference of tens to hundreds of miles away from the volcano. These eruptions can extensively cause a change to the global climate too. Hazards from quiet eruptions include lava flows which contain exploding fires and creating gas clouds which are rich in chlorine where lava pours into the sea. This can cause damage to wildlife and sea creatures.</span>
