... lone-pair electrons that can accept hydrogen bonds but cannot donate hydrogen bonds, the higher reactivity of the substrate with 2′-OH than 2′-F at U(–1) suggests that hydrogen-bond donation from the 2′-OH of U(–1) might be important. A hydrogen bond from this 2′-OH to the neighboring 3′-oxygen is t ...

... If H is increased by keeping E constant, then the radius of curvature r will decrease to keep m/e value constant in the above equation. So ion will change its position for falling on the electrometer. By changing either electric field or magnetic field, the ion of particular m/e value can be made to ...

... (iii) Ethylamine and aniline can be distinguished using the azo-dye test. A dye is obtained when aromatic amines react with HNO (NaNO + dil.HCl) at 0-5°C, followed by a reaction with the alkaline solution of 2-naphthol. The dye is usually yellow, red, or orange in colour. Aliphatic amines give a bri ...
