Answer» tion: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−4then P(−1)=(−1) 2 −(3×−1)−4=0and P(4)=(4) 2 −(3×4)−4=0∴ -1 and 4 are called the zeros of the quadratic polynomial x 2 −3x−4The 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 |
