H 3 C − C H = C H 2 + H C l—————–> in the presence of peroxide the intermediate of reaction is
Ch3-c+h—-Ch3 Because peroxide will work in the presence of HBr not in the presence of HCl.
For the reaction, C 2 H 5 O H + H X Z n X 2 ⟶ C 2 H 5 X , the order of reactivity is
Because the reaction follows SN1 mechanism and hence the halide formed is stable when it is of a larger size and size increases down the group. HI>HCL>HBr
Which reaction is not a redox reaction
i) H2 + Cl2 ——> 2Hcl ii) BaCl2 + NaSo4——->BaSo4 +2NaCl iii) Zn + CuSo4——-> ZnSo4 + Cu Vi) 2Kclo3I2——->2KIO3 + Cl2 Answer BaCl2 + NaSo4——->BaSo4 +2NaCl Explanation H2 + Cl2 → 2HCl is an oxidation-reduction (redox) reaction. Oxidation: Hydrogen atoms in H2 lose electrons and become oxidized to H+ Reduction: Chlorine atoms in Cl2 … Read more

In a 100 m race Kamal defeats Bimal by 5 seconds. If the speed of Kamal is 18kmph, then the speed of Bimal is
Solution Time taken by Kamal 100/ 18X5/18 = 20 seconds Time taken by Bimal 20+5 = 25 100/25 4X18/5 14.4 kmph Answer 14.4kmph
The ratio of income in two consecutive years is 2:3 respectively. The ratio of their expenditure is 5:9. Income of second year is 45000 and expenditure of 1st year is rs 25000. Saving in both years together is
Details solution Give data. Income 2:3 Expenditure 5:9 Income of second year = 45000 Expenditure in first year = 25000 Calculation Let the income of first year = X Expenditure in second year = Y As per question X/45000 = 2/3 3x= 90000 X = 30000 And 25000/Y = 5/9 5Y= 225000 Y = 45000 … Read more
