1.

2-METHYLPENTANE, molecular formula c6h14, is a colorless transparent liquid. Mainly used as solvent, organic synthesis intermediates, chemical reagents. Steam or fog is irritating to eyes and upper respiratory tract. Irritating to the skin. Burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting occurred after contact. The pollution of surface water, soil, atmosphere and drinking water should be paid special attention

2. Molecular formula: c6h14
structural formula: ch3-ch (CH3) - ch2-ch2-ch3
3. This is 3-methylpentane. If there are two ethyls on the methylene carbon, then these two ethyls and methylene carbon are the longest carbon chain - five carbons. The methyl on the methylene carbon, no matter from which end, is in the third position of the longest carbon chain, so it is 3-methylpentane
4. Dimethylpentane
5.

Store in a cool and ventilated warehouse. Keep away from fire and heat source. The storage temperature should not exceed 29 ℃. Keep the container sealed. It should be stored separately from oxidant and avoid mixed storage. Explosion proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are easy to proce sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials

6.

Organic synthesis, solvent. Gas chromatographic analysis standard. Used as solvent, intermediate of organic synthesis and chemical reagent

7. Either:
2,2-dimethylpentane
either:
2,3-dimethylpentane
or:
2,4-dimethylpentane.
because it is characterized by "two", that is, two methyl groups, its position should be corresponding with Arabic numerals.
8. Unknown_Error
9. Hello, there are six kinds of hydrogen. If you want to find the equivalent hydrogen, you should first draw the structural formula of the organic matter, and then draw the symmetry axis of the organic matter. Be sure to draw all the symmetry axes. Only one part is left in the two parts of the symmetry axis, and then any number of hydrogen on a carbon in this part can only be counted as one. How many kinds of equivalent hydrogen are there Pentane has no axis of symmetry! So if there are several carbons with hydrogen, there are several equivalent hydrogens. There are six carbons with hydrogen, so there are six equivalent hydrogens
10. The latter two are the same. With bromine water, the fading one is olefin, and the unreacted one is 2-METHYLPENTANE
