While both carbohydrates and lipids are made up of carbon, hydrogen and oxygen there are several differences:
1. Carbohydrates are chains of 2 or more carbon atoms. These can be very lengthy (like long cellulose chains of glucose units). They have many polar OH groups (e.g. glucose - C6H6O6). Most carbohydrates are hydrophilic and are soluble in water because of their polar OH groups. They are not necessarily sugars nor are they necessarily sweet. They are also important components of DNA, RNA and ATP.
2. Lipids are more diverse in their chemistry. They generally have a polar region at one end (this end attracts water) and a large non polar hydrocarbon region that repels water. Lipids don't dissolve in water and instead clump together with their hydrocarbon regions on the interior. Lipids include oils, fatty acids, waxes, steroids and hormones.

The primary difference between carbohydrates and lipids is that carbohydrates are soluble in water, polar, and hydrophilic in nature due to the presence of the -OH group while the lipid molecules are insoluble in water, hydrophobic in nature, and non-polar.
What other compounds in which lipids are soluble?
Lipids are soluble in a non-polar solvent like benzene, chloroform, and ether.
Carbohydrates do not have the ability to store energy, while lipids are molecules that store energy. Carbohydrates form DNA, RNA, etc, while lipids form hormones, steroids, waxes, etc.
Carbohydrates are normally found in saturated form (presence of single bonds), while lipids are found in saturated as well as unsaturated form.
Therefore, it is well described above.
