In diamond, each carbon atom is bonded to four other carbon atoms to form (a) a hexagonal array (b) a rigid three-dimensional structure (c) a structure in the shape of a football (d) a structure of a ring. A soap molecule has a … A soap molecule has a (a) hydrophobic head and hydrophobic tail (b) hydrophobic head and hydrophilic tail (c) hydrophilic head and hydrophilic tail Answer: (a) Solution: A homologous series is a group of organic compounds having similar structures and similar chemical properties in which the successive compounds differ by group.. hfp-wrgi-bckXxx for showing [email protected] hfp-wrgi-bckXxx for fun and enjoy , for boys and girls fu**ing come Which of the given is a noble gas? How many electrons are there in the outermost shell of carbon? The first member, the first homologue, of the alkyne homologous series must contain 2 carbon atoms which are joined by a triple bond, and, because each carbon atom must make 4 bonds in total, each of the carbon atoms must be bonded to 1 hydrogen atom as shown below: The alkynes comprise a series of carbon‐ and hydrogen‐based compounds that contain at least one triple bond. Answer. The first member of alkyne homologous series is ethyne C2H2 chijithjerin chijithjerin Answer: ethyne. 1 B. A. This group of compounds is a homologous series with the general molecular formula of C n H 2 n‐‐2 , where n equals any integer greater than one. General Formula CnH2n CnH2n-2 CnH2n+2 IUPAC name of the homologous series Alkenes Alkynes Alkanes Characteristic bond tyres Double bond Triple bond Single IUPAC name of first member of the series Ethene Ethyne Ethane Types of reaction with chlorine Addition Addition subsitiution Fill in the blanks: The first member of homologous series among alkynes is _____. Answer (b) ethyne. 19. A. Can you explain this answer? The Alkene series is similar to the Alkane series except that each carbon chain has one, and only one, double bond in it. The firSt member of the alkyne homologous series is (a) propyne (b) ethyne (c) methane (d) ethene. Answer. are solved by group of students and teacher of SSC, which is also the largest student community of SSC. Explanation: New questions in Chemistry. Carbon B. Argon C. Nitrogen D. Hydrogen 34. Write the name and molecular formula of the first member of the homologous series of alkynes. Answer: b. An Alkene is a Hydrocarbon which means that it is a molecule made up entirely of Carbon and Hydrogen atoms. asked Jul 12, 2018 in Chemistry by Anukriti bharti ( 38.1k points) carbon and its compounds In diamond, each carbon atom is bonded to four other carbon atoms to form (a) a hexagonal array (b) a rigid three-dimensional structure (c) a structure in the shape of a football (d) a structure of a ring. 18. 19. The first member of the alkyne homologous series is (a) propyne (b) ethyne (c) methane (d) ethene. The firSt member of the alkyne homologous series is (a) propyne (b) ethyne (c) methane (d) ethene (b) ethyne. Answer: b. The odour of acetic acid resembles that of (a) Rose (b) Burning Plastic (c) Vinegar (d) Kerosene (c) Vinegar. The first member of alkyne homologous series is ethyne as you need 2 carbons minimum to have a carbon connected with double bond. The first member of alkyne homologous series is: A. Ethyne B. Ethene C. Propyne D. Methane 33. The Questions and Answers of The First member of homologous series of alkene isa)Metheneb)Ethenec)Propened)ButeneCorrect answer is option 'B'. The firSt member of the alkyne homologous series is (a) propyne (b) ethyne (c) methane (d) ethene. Since the element Carbon bonds four ways and the element Hydrogen bonds only one way we can easily construct the members of this series. 19. 2 C. 3 D. 4 35. The general formula of alkyne is where n is the number of carbon atoms.
