Therefore, Order of basic strength is –NO2 has strong –R effect and –CH3 shows +R effect. Ask Question Asked 5 years ago. Following are the conjugate acids, I drew (I don't know if they're correct): According to me, due to resonance of the benzyl groups or lack of resonance, the order of basic strength should be: $$\mathrm{III > II > I > IV}$$ But the answer given is: Aniline. Compare the alkali metals and alkaline earth metals with respect to (a) ionisation enthalpy, (b) basicity of oxides and (c ) solubility of hydroxides. Dec 07,2020 - The correct order of basic-strength of oxides of alkaline earth metals is -a)BeO > MgO > CaO > SrOb)SrO > CaO > MgO > BeOc)BeO > CaO > MgO > SrOd)SrO > MgO > CaO > BeOCorrect answer is option 'D'. In part (a) NO2 is at p-position hence will attract e- density by both –M and –I In part (b) NO2 is at m-position hence will attract e- density by –I only Therefore is no such effect in part (c) Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. Biology. • The number of muscle groups trained per workout needs to be considered when designing the resistance training program. I know that to compare the basic strengths, we need to find the stability of their conjugate acids. (i) Considering the inductive effect of alkyl groups, NH 3, C 2 H 5 NH 2, and (C 2 H 5) 2 NH can be arranged in the increasing order of their basic strengths as: NH 3 C2H5NH2 > CH3NH2 > NH3 > C6H5CH2NH2 > C6H5NH2. 8 years ago Disapproved.

Acetanilide. (A) NH3 < C2H5NH2 < #Explanation. Cloudflare Ray ID: 6103afee3ec5f98d Following are the conjugate acids, I drew (I don't know if they're correct): According to me, due to resonance of the benzyl groups or lack of resonance, the order of basic strength should be: $$\mathrm{III > II > I > IV}$$ But the answer given is: The correct increasing order of basic strength for the following compounds Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. You may need to download version 2.0 now from the Chrome Web Store. Basicity order of Nitrogen follows the order. Answer: Explaination: C 6 H 5 NH 2 < C 6 H 5 NHCH 3 < C 6 H 5 N(CH 3) 2 is the increasing order of basic strength because —CH 3 … Physics. Hence, the increasing order of the basic strengths of the given compounds is as follows: C 6 H 5 NH 2 < C 6 H 5 NHCH 3 < C 6 H 5 CH 2 NH 2. Ex.9 Compare the basic strength of the following. Therefore the decreasing order of basic strength in gas phase will be (C2H5)3N > (C2H5)2NH > C2H5NH2 > NH3. Chemistry. The correct option is D. Related. HNO2 Ka = 4.0 × 10-4 HF Ka =7.2×10-4 HCN Ka = 6.2 × 10-10 a.CN- >NO2- >F- >H2O>Cl-b.Cl- >H2O>F- >NO2- >CN- c. CN- >F- >NO2- >Cl- >H2O d.H2O>CN- >NO2- >F- >Cl-e. none of these The correct decreasing order of basic strength of the following species is ….. H_(2)O, NH_(3), OH^(-),NH_(2)^(-) Thus basic strength should decrease from 1 0 > 2 0 > 3 0. Basicity order of Nitrogen follows the order.
