What is the hybridization of carbon 1 (far left) and carbon 2 (middle) in this hydrocarbon: CH3CH=CH2? (A) sp³, sp (B) sp?, sp? (C) sp³, sp? (D) sp, sp?arrow_forwardFor the reaction CH 3 Br (aq) + OH - (aq) → CH 3 OH (aq) + Br- (aq) it is known that when the concentration of OH - doubles, the reaction rate doubles. When the concentration of CH 3 Br increases 1.2 times, the reaction rate increases 1.2 times. Write the rate equation for the reactionarrow_forwardAlthough CH4 reacts with Cl2 to form CH3Cl and HCl, the corresponding reaction of CH4 with I2 does not occur at an appreciable rate, even though the I–I bond is much weaker than the Cl–Cl bond. Explain why this is so.arrow_forward

I II III IVarrow_forwardMake an brief introduction about Catalysis in Chemistry.arrow_forwardThe following reaction proceeds at a rate such that 4 mole of AA is consumed per minute. Given this, how many moles of CC are produced per minute? 2A+2B→4Carrow_forward
- The rate law for the reaction H2(g) + 2NO(g) → N2O(g) + H2O(g) was experimentally determined to be rate = k [NO]2 [H2]. Which of the following statements is false? Doubling the concentrations of both reactants would double the reaction rate Tripling H2 concentration would triple the reaction rate The overall reaction order is 3 Decreasing NO concentration by half would decrease the reaction rate 4 timesarrow_forwardPlease include the reaction mechanism aswellarrow_forward1a. According to the mechanism of bromination, what is the intermediate’s structure of the following reaction 1b. According to the mechanism, what is the intermediate’s structure of the following reactionarrow_forward
- Assuming that the mechanism for the hydrogenation of C2H4 given in Section 11-7 is correct, would you predict that the product of the reaction of C2H4. with D2 would be CH2DCH2D or CHD2CH3? How could the reaction of C2H4 with D2 be used to confirm the mechanism for the hydrogenation of C2H4 given in Section 11-7?arrow_forwardDistinguish between the differential rate law and the integrated rate law. Which of these is often called just the rate law? What is k in a rate law, and what are orders in a rate law? Explain.arrow_forwardDetermine the first step of this mechanism.arrow_forward
