Organic Chemistry - Some Basic Principles and Tech

The major product 'A' of the following given reaction has _________ sp² hybridized carbon atoms.

2, 7-Dimethyl 1-2-6- octadiene  A

Major Product

Number of electrophilic centres in the given compounds is _________.

A 0.166 g sample of an organic compound was digested with conc. H₂SO₄ and then distilled with NaOH. The ammonia gas evolved was passed through 50.0 mL of 0.5 N H₂SO₄. The used acid required 30.0 mL of 0.25 N NaOH for complete neutralization. The mass percentage of nitrogen in the organic compound is ___________.

Identify A in the given reaction.

In the estimation of bromine, 0.5g of an organic compound gave 0.40g of silver bromide. The percentage of bromine in the given compound is____________% (Nearest integer)

(Relative atomic masses of Ag and Br are 18 u and 80 u, respectively).

12.2. Assertion: Citric acid is namedso because it is found in citrus fruits.

Reason: Prior to IUPAC system of nomenclature, organic compounds were assigned

names based on their origin or other properties.

12.41. Assertion: In general, π bonds provide the most reactive centres in the molecules containingmultiple bonds.

Reason: The electron charge cloud of the π bond is located above and below the plane of bonding atoms. The electrons being easily available to the attacking reagents.

12.36. In the organic compound CH2 = CH – CH2 – CH2 – C ≡ CH, the pair of hybridised orbitals involved in the formation of: C2 – C3 bond is:

(a) sp – sp² (b) sp – sp³ (c) sp² – sp³ (d) sp³ – sp³

12.16. For the following bond cleavages, use curved-arrows to show the electron flow and classify each as homolysis or heterolysis. Identify reactive intermediate produced as free radical, carbocation and carbanion.
