A triple bond consists of one pie bond and two Sigma bonds. This is false.

<h3 /><h3>Does a triple bond have 2 pi bonds?</h3>

A triple bond in an alkyne consists of one sigma bond and two pi bonds. As a result of the geometry of the sp hybrid orbitals, the two carbon atoms of the triple bond and the two atoms directly attached are collinear.

<h3>Is a triple bond a pi bond?</h3>

A triple bond consists of two pi bonds and one sigma bond. A double bond contains one sigma and one pi bond. Single bonds are always sigma bonds.

<h3>How many electrons are in a triple bond?</h3>

Triple bond: A covalent bond of bond order = 3, consisting of six electrons; one pair in a sigma bond and the other pairs in pi bonds.

two perfumes A and B were released at the same time and you are standing 7.5metres away from both of them.molarmass of perfume A
kifflom [539]

17.40 sec is the time will take to smell second perfume after diffusion takes place

Acc. to Graham's law of Diffusion

Diffusion of Gas inversely proportional to square root of its Molecular mass.

<u>rb (Perfume B)</u>

ra(perfume A)

= \sqrt{\frac{Ma}{Mb} } its equation (1)

Give molar mass of Perfume A = 275 g/mol

molar mass of Perfume B= 205g/mol putting value in (1)

» \frac{rb}{ra}=\sqrt{\frac{275}{205} }

\frac{rb}{ra} =1.16<em> its eq (2)</em>

» Perfume B will defuse 1:16 times faster than perfume A.

Hence, perfume B will be first smelled by Person.

Sf Equal volume V of two goes diffuse in t1 and t2 sec. respectively ton

\frac{ra}{rb}=\frac{tb}{ta}

Now,, from eq(2) toto

1/1:15 = \frac{tb}{ta}

ta

Given tb =the smell of Perfume B as it diffuse faster  

ta= 1.15 x 15 see  

=ta2=17.40 sec
