Q:

Which of the following is the most stable carbocation?

Screenshot_(8)1522302473.png image

A) 4	B) 3
C) 2	D) 1

Answer & Explanation Answer: C) 2

Explanation:

Here the most stable carbocation is the option (2).

Carbocations are always hungry for electrons. The stability of carbocations increases from primary to secondary to tertiary. Here, option (c) shows the most stable carbocation because it can easily withdraw electrons from two other carbon atoms and the more electronegative oxygen atom.

Carbocation stability depends on hyperconjugation. The tertiary carbocation is stabilized by electron releasing inductive effect.

Q:

What is the output after compile and run the following code ?

int Output = 10;
boolean b = false;
if((b == true) && ((Output += 10) == 20))
{
System.out.println("We are equal " + Output);
}
else
{
System.out.println("Not equal! " + Output);
}

A) Compilation and output of "We are equal 10"	B) Compilation and output of "Not equal! 10"
C) Compilation error, attempting to perform binary comparison on logical data type	D) Compilation and output of "Not equal! 20"

Answer & Explanation Answer: B) Compilation and output of "Not equal! 10"

Explanation:

The output will be "Not equal! 10". Please note that && is logical AND operator. If first operand before (&&) is false then the other operand will not be evaluated. This illustrates that the Output +=10 calculation was never performed because processing stopped after the first operand was evaluated to be false. If you change the value of b1 to true, processing occurs as you would expect and the output would be "We are equal 20".
