Which base would always be appropriate to deprotonate the carbon that is ? to a carbonyl carbonyl? lithium diisopropylamide sodium amide sodium ethoxide n-butyl lithium Solution Since, the hydrogen on the ? carbon is weakly acidic, so it reaquires strong base like lithium Diisopropylamide(LDA) to form stable enolate ion. Ie CH3(C=O)CH3 + LDA - - - > - CH2(C=O)CH3 (enolate ion) And this enolate form is resonance stabilzed. - ?CH2(C=O) CH3(enolate ) <-----> CH2=C(OH) CH3(enol) Note : this reaction can also be possible with sodium ethoxide also but being a weak base the deprotonatelion take place only to extent 0.1%. .

When equal moles of the following acids are dissolved in 1 L of H 2 O, which acidic solution will have lowest concentration of ions? HI HF HClO4 HNO 3 HCl Please explain why! Solution All the acids given are the strongest acids. But among all, HI > HBr > HClO 4 > HCl > HNO 3 The above order it the acidic strength. Among all the given acids, HI is the strongest and HNO3 is the weakest. Strongest acid dissociates completely in H 2 O (There will not be any undissociated molecule). But due to the common ion effect(H + ), the HNO 3 acid will have lowest concentrations of ions. Thanks and hope u got the answer. .

What will happen to the Ksp value of Al(OH)3 when sodium hydroxide is added to the solution? Explain why Without doing a calculation, predict which of the following has the greatest molar solubility in water? AgCl (Ksp = 1.8 x 10^-10) AgBr (Ksp = 5.0 x 10^-13) AgI (Ksp = 8.3 x 10^-17) Solution 1) Solubility equation of Al(OH)3 is: Al(OH)3Â Â <â€”>Â Â Al3+Â Â (aq) + 3 OH- (aq) Adding NaOH is like adding product (OH-) Adding product will shift the reaction in the direction of reactant as per Le chatelier Principle So, Equilibrium moves to reactant side This will decrease solubility Answer: solubility decreases 2) All of them are of same form AX So, the one with the greatest value of Ksp will have greatest molar solubility Answer: AgCl .

Which of the following can be used to create a VPN (Virtual Private Network)? A. PPP (Point-to-Point Protocol). B. PPTP (Point-to-Point Tunneling Protocol). C. SLIP (Serial Line Internet Protocol). D. ESLIP (Encrypted Serial Line Internet Protocol). Solution B. PPTP (Point-to-Point Tunneling Protocol). Tunneling refers creating a virtual dedicated connection between two systems or networks. You create the tunnel between the two ends by encapsulating the data in a mutually-agreed-upon protocol for transmission. In most tunnels, the data passed through the tunnel appears at the other side as part of the network. Point to point tunneling protocol was originally proposed by Microsoft and its associates and it works by embedding its very own network protocol within the TCP/IP packets. .

What type of intermolecular forces exist in NH3 and H2S? dispersion forces, dispersion forces and H-bond, dispersion forces & dipole-dipole forces Solution In NH 3 ,intermolecular forces present are hydrogen bonds . The hydrogen bonds are many magnitudes stronger than other intermolecular forces in NH 3 . In H 2 S , Sulfur atom have 6 valency electrons and hydrogen atoms have 2 valence electrons. The central sulfur atoms has 4 entities around it. Two hydrogen atoms, and two lone non-bonding electron pairs. According to VSEPR theory, this means that the shape of the molecule is bent and because of the asymmetrical shape, the molecule is polar.The intermolecular force which polar molecules take part in are d ipole-dipole forces . .
