CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317305 The first organic compound was synthesized in laboratory by

1 Wohler

2 Kolbe

3 Berzelius

4 Neil Berthelot

CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317306 The first carbon compound prepared from its elements is

1 Urea

2 Acetic acid

3 Methane

4 Benzene

CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317307 The first Nobel prize in Chemistry was given to

1 JH van't Hoff

2 Cannizzaro

3 Mendeleev's

4 Moseley

Explanation:

JH van't Hoff was the scientist who got first nobel prize in Chemistry.He predicted in 1874 that the four bonds of a carbon atom are directed towards the four corners of a regular tetrahedron and the angle between any two adjacent bonds is $109^{\circ} 28^{'}$ . This tetrahedron arrangement of four bonds of carbon laid the foundation of the present day fascinating field of 'stereochemistry'.
