Alkenes are ______. Saturated Unreactive Single bonds Very reactive

1 answer:

5 0

Answer:
Alkenes are <u>Very Reactive</u>.

Explanation:
Other options are incorrect because;

Saturated compounds are those hydrocarbons which contains only single bonds, while alkenes contain atleast one double bond.

Single bonds again stands for saturated compounds, hence it is false.

Alkene are reactive because the double bond has the potential to open by addition reaction. So electrophiles are readily added across double bond. This reactivity can also be explained by the exposure of nucleophilic double bond above and below the plane, which is highly exposed to incoming electrophiles.

Tin has many possible isotopes. Three of these isotopes are 116sn, 120sn, and 126sn. What is the mass number of each? How many p

Aneli [31]

Isotopes are defined as atoms of same element with different mass number and same atomic number.

Here, atomic number is equal to number of protons and number of electrons, it is denoted by symbol Z thus,

$Z=n_{e}=n_{p}$

and, mass number is equal to sum of number of protons and neutrons, it is denoted by symbol A thus,

$A=n_{p}+n_{n}$

The three isotopes of tin are given, Sn-116, Sn-120 and Sn-126, mass number for these three isotopes is 116, 120 and 126 respectively. Since, they are isotopes thus, atomic number remains the same that is 50.

Since, $Z=n_{e}=n_{p}$ thus, number of protons and electrons will be 50.

For Sn-116,

$A=n_{p}+n_{n}$

Or,

$116=50+n_{n}$

Or,

$n_{n}=116-50=66$

For Sn-120,

$n_{n}=120-50=70$

For Sn-126,

$n_{n}=126-50=76$

Therefore, mass number, number of protons, electrons and neutrons in all three isotopes are:

Sn-116:

Mass number= 116

Protons=50

neutrons=66

electrons=50

Sn-120:

Protons=50

neutrons=70

electrons=50

Sn-126:

Protons=50

neutrons=76

electrons=50
