Question

Write the instruction to set external interrupt O.

Answer 1

Amines contain a nitrogen atom with a lone pair of electrons. They are basically the derivatives of ammonia. If we replace one or more hydrogen atoms by substituent groups such as alkyl or aryl in Ammonia, we get a new class of organic compounds called Amines. Examples of significant amine structure include Amino acids, biogenic amine, trimethylamine, and aniline.

Physical properties of amines

Classification of Amines

Amines are classified into four categories namely, primary, secondary, tertiary and cyclic. A primary amine is one when you can replace one of the three hydrogen atoms by an alkyl or aryl group. When you can replace two out of three hydrogen atoms, we get secondary amine.

Similarly, when all the three hydrogen atoms are replaced tertiary amines are formed. Only secondary or tertiary amines can be cyclic. The 3 – member ring aziridine is an example of cyclic amine. Let us now look at the physical properties of amines in brief.1

In figure O is the centre of a circle of radius 5 cm.T is a point such that OT=13CM and OT intersects the circle at E.if AB is the tangent to the circle at E.find AB. sorry no figure i hope somebody can find it out

OP is equals to a radius is equals to 5 let AE equals to BE be x.

in triangle OPT, OP²+OT²=PT²

Then, PT=12cm.

Now, AT=12-x and AE=x

And TE=13-5=8cm.

Now in triangle AET, AT²=AE²-ET²

x= 10/3cm.

AB=AE+ BE =2x=2×10/3=20/3cm.
