Question

what is confirmation . how will you obtain 1- bromopropane &2- bromopropane from propene . explain by chemical reaction . ​

Answer 1

Explanation:

The zero of the polynomial is defined as any real value of x, for which the value of the polynomial becomes zero.

A real number k is a zero of a polynomial p(x), if p(k) = 0.

For example P(x)=x

2

−3x−4

then P(−1)=(−1)

2

−(3×−1)−4=0

and P(4)=(4)

2

−(3×4)−4=0

∴ -1 and 4 are called the zeros of the quadratic polynomial x

2

−3x−4

The addition of hydrogen halide to an unsymmetrical alkene gives two products. Propene on reaction with hydrogen bromide forms 80 % 2- bromopropane (isopropyl bromide) and 20% 1-bromopropane(n-propyl bromide)

Propene when reacted with HBr in presence of peroxide, it gives 1,-Bromopropane. The addition is according to Anti Markovnikovs rule.

Addition of HBr to propene gives 2- bromopropane. The hydrogen of HBr adds to Carbon 1 of propene and bromine adds to Carbon 2
