Okay, so first of all, we should keep in mind the light dissolves like rule, which says that the polar solute dissolved very well in the polar solvent and the non -polar solute dissolved very well in the non -polar solvent, vice versa.
00:15
So that is difficult.
00:18
Okay.
00:19
Now, so lipids are non -polar in nature.
00:35
Being non -polar means that they are, they lack polypolar.
00:39
So now by like dissolves like rule known polar solute messable that is can dissolve completely in non polar solvent only.
01:30
So here we have given options we have to check whether the given solvent is the non -polar or polar okay so number one a part so we have ch3 ch2 whole 7 ch3 so if you open this carbon chain you will find out that it is a hydrocarbon chain okay it's straight hydrocarbon channel okay and hydrocarbon so they are non -polar in nature okay so the hydrocarbons are non polar in nature then moving on to next we have ch3 cl okay now let me draw this structure completely so this can also be drawn like we have here one chloro group attached and three hydrogen items are being attached in tetrahedral manner so now chlorine is more electron negative than carbon okay so now it will have partial negative charge all its electron density with the it has tendency to withdraw the electron density towards itself and that's why all the electron density of carbon being withdrawn towards this glory inside hydrogen are less electron negative okay so that's why we can see that we have partial positive charge on hydrogen okay as compared to carbon we are considering okay so that's why we can say that so the direction of dipole moment that will be from hydrogen to carbon and carbon to chlorine okay so now so we have here you can see that there is unequal asymmetric dipole movement okay so net dipole moment we have certain amount of value for net dipole moment okay so that's why this molecule is polar.
04:00
Okay, since we have certain amount of net dipole moment, this molecule is polar.
04:07
There is polarity.
04:09
Okay, because polarity arise due to asymmetrical distribution of charges, okay? or unequal distribution of charges.
04:17
Polar due to unequal distribution of charges.
04:42
C part is ccl4.
04:47
So now let me draw the structure we have to the carbon atom we have four chlorine atom at test...
