Maths-

The system of equations $alpha x plus y plus z equals alpha minus 1 x plus alpha y plus z equals alpha minus 1 x plus y plus alpha z equals alpha minus 1$ has no solution, if $alpha$ is

Maths-General

– 2
1
Either – 2 or 1
Not – 2

Answer:The correct answer is: – 2For no solution or infinitely many solutions $open vertical bar table row alpha 1 1 row 1 alpha 1 row 1 1 alpha end table close vertical bar equals 0 rightwards double arrow alpha equals 1 comma alpha equals negative 2$ .
But for $alpha equals 1$ , clearly there are infinitely many solutions and when we put $alpha equals negative 2$ in given system of equations and adding them together L.H.S $not equal to$ R.H.S. i.e., No solution.

The compound that will react most readily with $N a O H$ to form methanol is:

open parentheses C H subscript 3 close parentheses subscript 4 N to the power of plus I to the power of minus not stretchy ⟶ with N a O H on top open parentheses C H subscript 3 close parentheses subscript 4 N to the power of plus O H to the power of minus not stretchy rightwards arrow with straight capital delta on top open parentheses C H subscript 3 close parentheses subscript 3 N plus C H subscript 3 O H

The reaction is more spontaneous for a better leaving group,

I to the power of minus

Also, methyl group with

plus N

will disperse

plus v e space

I to the power of minus

easily.

Alcohols may behave as:

Alcohols are neutral as they do not influence the pH. Due to — bond, they possess Bronsted acid nature showing cleavage of — bond. Also due to the presence of lone pair of electron on oxygen atom, they act as Lewis base. The reactivity order is based on of alkyl groups.
Lewis base order :

3 space ͦ greater than 2 space ͦ greater than 1 space ͦ

Bronsted acid order :

1 space ͦ greater than 2 space ͦ greater than 3 space ͦ
